first 40 determinations of the absolute age by means of the
argon method made more precise ideas possible concerning the
structure of the aforesaid plateau. Several results were sur-
prising and their geological interpretation meets with sarious
difficulties (Table 1). The highest age, i. ea. 1020-1270 Mil-'
lion years were obtained,at first for the oases Langeneset,
Grirson, Banger, and Obruchev, i. e. for leucocratic granites
and pegmatites. The aGe of the weakly migmatuitic (Banger oasis
andother regions of the crystalline basement) ro@ks fluctuates
between 940 and 1050 million years. So-called poly-migmatites
which are 700-730 million years old occur at the same time at
several places, especially in the Banger oasis. Thus two migma-
titization stages can be separated: a) an earlier one which
occurred more than 1000 million years ago, and b) a late one
- more than 700 million years ago. Thus the migmatitization of
the oldest masses of the eastern Antarctic belongs to the Pro-
terozoic. A packet of gnelsses in the region of the Einsvort
bay and the Villson. elevation is for the time being the only
exception. Weakly migm-atitized biotite-gneisses are here 425-
485 million years old. This agrees almost- with the age of the

here occurring porphyroblastic C;ranites. The age of the green
schists and mica phyllites (middle stage of the plateau) fluc-
tuates between 400 and 500 million years. This corresponds -to
Sinisian and Lower Cambrian. The Rapakivi granites in the ex.-
4.
Ureme east of the investigated region has approximately -the
same age. The most recent Granitoids are the subalkal-ine bio--
tite-hornblende varieties. They are Caledonian, with an age of
305-315 million yea-ra. The age of the gabbro-dolerite from a
stratiform intrusion within the Bikon (Beakon) series (170
million years old) agrees --,,ather well with the geological po-
sition (Lower Triass-.1Lc). The same holds in the case of Terti-
ary leucite-granite (mountain Gauss) which is approximately
20 million years old. The age determinations of the ment�oned
rocks confirm on the whole the authors' assumption concerning
the 3-stage structure of the plateau. The old'Gerling constant
Xk= 6.02010- 11 year-1 which is much used in the USSR was used
for the determination. The data are only temporary and prcbably

TITLE: Isotopic Composition of Lead in Iron Meteorites
PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 128, Nr 4, pp 688-690
USSR
ABSTRACT: C. Patterson et al. (Refs 1,3) found the same composition
with respect to lead isotopes in 3 different meteorites,
i.e. Pb 204 1; Pb 2o6 9.5; Pb 207 10.4; Pb 208 29-5. His data are
in good accordance with the theoretically predicted isotopic
composition of lead in iron meteorites. Several authors
theoretically computed the isotopic composition of the original
lead, extrapolating back into the past (4-5 billion years) the
change in the isotopic composition of the lead of varying age
found in ore. The values obtained in this way are close to
those established experimentally by Patterson. The authors
intended to carry otit a close investigation of the problem
mentioned in the title. They first examined the lead content
Card 1/4 of the Sikhote-Alin' and Chinge meteorites (I. Ye. Starik,

Isotopic composition of Lead in Iron Meteorites SOV120-128-4-14165
E. V. Sobotovich, G. P. Lovtsyus, Ref 2). The lead content
of thownteorites in the metallic phase is less by at least
one order of magnitude than that published by Patterson for
the Ca?ion Diavolo meteorite (3-7-10- 7 g1g). The isotopic
composition of the troilite and of the metallic phase of the
Sikhote-Alin' meteorite are entirely different from the
Patterson data. Because of this discrepancy the authors
analyzed the meteorites examined by Patterson. The meteorite
samples were chemically separated and the lead was pyro-
chemically removed (E. V. Sobotovich, Ref 4). Table 1: degree
of impurity of the meteorite caused by foreign lead. This
impurity caused by foreign lead is only 10-24@4. Assuming that
iron meteorites contain original lead, the impurity by oidinaiy
lead must be at least 10OVIo of its cosmic content. These-
experiments confirmed the results obtained on content and
isotopic composition of the lead in the analyzed iron meteor-
ites and they made possible to introduce a correction for
the foreign-lead impurity. Table 2 contains data on the iso-
topic composition of the lead in 3 iron meteorites and the
Card 2/4 troilites contained in them. According to it the composition

isotopic Composition of Lead in Iron Meteorites SOV/20-128-4-14/65
of the Sikhote-Alin' and Hanbury meteorites is the usual
and the isotopic composition of the lead in the ore is
analoguous to an age of several hundreds of millions of
years. The results obtained by the authors are factually
valid for the lead contained in the iron meteorite and they
cannot be explained by impurities caused by ordinary lead
during the analysis. According to the reeults of the present
paper the meteorites have no common genesis in spite of the
generally accepted theory. Possibly some of them do not
belong to our solar system or they were formed under con-
ditions when lead originating from radioactive processes
was already present. These meteorites therefore cannot be
as old as was previously assumed. If these meteorites do
not originate from our solar system, nothing precise can
be'said about them. If they come from our solar system they
have developed 400-500 millions of years ago. The authors
express their abknowledgements to the Komitet po meteoritam
AN SSSR (Committee for I'leteorites of the AS USSR) and the
Estonskiy geologicheskiy institut (Estonian Geological
Institute) for putting at their disposal the meteorite samples.

ABSTRACT: The radioactivity of the sediments in the enclosed aeas is al-
most uninvestigated. The Black Sea shows characteristic hydro-
logical and hydroahemical codditions. It is also intensively fed
with sedimentary material. For this reason its sedimentation
strongly differs from that in large wasini waters (Ref 5). In
this connection the authors wanted to explain the influence of
these specific conditions on the sedimentation and-.On the type
of distribution of the radio elements in.-the Black-Sea bottom
sediments. The results achieved are not sufficient to draw final
conolusions.-For this reason only some assumptione are expreeiid.
The authors studied the vertical distrlbution.df.uranium$ radium,

taken from the central part of 'the Blacli *ea from a depth of

Distribution of Radio Elements in the S'ediments of the Black Sea
consisted of extremely fine-disperse mud with thin sapropel in-
termediate strata. Figure I shows the vertical distribution of
the above-mentioned elements in the core. Table 1'gives the cor-
responding figures. From these data it may be concluded that
in the upper horizonq of the core the radioactive equilibrium
in the'uranium series in widely disturbed; the ionium content
ie almost 4 times higher,than the amount corresponding to the
equilibrium with uranium; the radium oontentp however, oonati-
tutes only 1/4 of this amount.. The radium content in the water
of the Black Sea is only 1'5@6 of the equil-ibrium, value of uranium
dissolved in the water. Thus the radium-content in the sediment
is hardly one fourth of the amount which -should be measured if
85@6 of the radium were sedimeniated from the water. Assuming.that
no radium migration'tikes place in the oDres of marine sediments
(Ref 1) the discrepane'lin the radium balan" in the water and
in the sediment of the Black Sea may-be explained by radium
,leaching from the sediment in itb upper layers. On the other
.hand, the upper horizons are considerably earichad with ionium.

methods. The main bulk of iron, however, is transported into the
deep-seated sediments with the river water. The authors conclude
therefrom that the v4rtical CaCO ,-distribution reflects the chan=e
of the chemical conditions in tha course . of time. Since t'l,.e ver-,
tical distribution of ionium and uranium agrees with V'-. Of
CaCO3 it indicates that the main amount of ionium an-' n_-_:. iun
was -separated from the solution. On the other hand it. may be
concluded from the pArallel change in -the thorium content with V
thptt of iron that the major part of thorium is of terrigenous
origin. The authors calculated the rate of sedimentation in the
Black Sea from the data from table 1. It is 12-13 cm within
thousand years. If it is however assumed-that in the horizon
100-106 cm the equilibrium between ionium-and uranium is still
attained (Fig 2) the rate of sedimentation is only 0-4-0-5 cm
per 1000 years. The problem as to which of the two values 3.9.
correct has hitherto not been definitely solved. There are 2
figures, 1 table, and 6 references, 4 of.which are Soviet.

TITLE: Lead and Its Isotopic Composition in Iron Meteorites
PERIODICAL: Doklady Akademii nauk SSSR, 196o, vol. 134, No. 3,
pp. 555 - 558
TEXT: By way of introduction the authors refer to their discovery
(Ref. 1) that meteorites contain lead with various isotopic compositions
The present article deals with the investigation of all main groups of
iron meteorites (octahedrites of various structureg hexahedrites, and
ataxites). From two to three quantitative analyses were made on all of
the 12 meteorites investigated, and the isotopic composition of lead
was determined at the same time. The results tabulated in Table 1 show
that in the majority of these meteorites the isotopic composition of
lead corresponds to that of terrestrial lead. No intermediate isotopic
composition of lead was discovered. Judging from their composition, the

Meteorites Boig/Bo6o
12 meteorites can be classified into two-groups. The first ,-ompr-4ses
four meteorites of the same isotopic composition of lead as was first
ascertained by Patterson (Ref. 2) and later by the authors themselves.
These meteorites are octahedrites of various structures and contain
1 -"2-10-7 g Pb'per gram. The second group comprises the remaining eight
meteorites containing lead with an isotopic composition corresponding
to terrestrial lead of various ages. All principal meteoritic groups ar
represented here. All hexahedrites and ataxites thus belong to that
group which contains lead in terrestrial isotopic composition. In them)
the lead concentration lies at the lower distribution limit of
2 - 4-10-8 g Pb per gram. The same lead content was established for
coarsely structured octahedrites. A lead content of 2-10-7 g Pb per gram
was found for medium-structured octahedrites. The first group did not
exhibit any marked inhomogeneity in the lead distribution, while the
inhomogeneous lead distribution in the second group accounted for dif-
ficulties encountered in the determination of the lead content. There
are cases in which meteoritic surface zones contain more or less lead

than the core. Closer studies are required to explain this. No relation-
ship was established between the lead content and the isotopic composi-
tion on the one hand, and the type and structure of iron meteorites on
the other. Reference is made to the one to two times larger lead content
in troilite inclusions as compared with the content in the iron-nickel
phase. Indications regarding the formation of iron meteorites were in-
ferred from the existence of the two groups. The conclusion is drawn
from the existence of two analogous groups in stony meteorites that the
analogous groups originate from a parental body. The authors-thank

TEXT., In an attempt to apply more widely the knowledge gained
recently in the field of radiochemistry to problems concerning the
kinetics and catalysis of chemical reactions, the author surveys
the results of his own and other studies concerning the mechanism
of adsorption of micro-quantities-of radioactive indicators on
solid surfaces, the absorption of electrolyte impurities from
solutions, distribution of radioisotope indicators-between the-,
solid and liquid phases etc. The problem is-approached from the,
practical point of viey and is studied on two basic processes'.

impurities by a precipitate during its-formation and the mechanism

A coincidence scintillation counter was designed for counting C and ben-
zene and ethylbenzene were used as the liquid scintillator solvents, syntiie_
sized according to the above-given scheme. Combined with a highly-effootive
counter these can be used to determine the absolute age up to 37,000 Years
in the case of ethylbenzene, and 48,000 Years in the case of benzene. I&
selecting a scintillation counting method the authors bass their attempts on
finding a substance which is easily prepared and does not require large

-@mounts of carbon$ so that the advantages of both the proportionate, and
scintillation methods could be combined. Ethylbonsone and benzone chosen
by the authors as the carriers of the natural carbon activity are said to
render the scintillation method applicable to young samples and in the case
of old ones'.inorease the sensitivity of the mothod. Ethylbonzone in rec COP-
mended from the following considerations# 1)92.3% from the sample can be
introduced into the othylbenzone molecule; 2) the othylbenzone molecule it-
golf is an excellent solvent of liquid saintills-tors, being inforio,r only to
the very boat solvents, much as toluene, xylons; 3) its preparation and ? u-
rifioation are simple and do not require complex apparatus or reagents
difficult to obtain; 4) for its synthesis a relatively low amount of carbon,
8@15 g, is required. The apparatus used by the authors to count natural
a 4 in describods the Y@otomultipliere function at room temperature, the
complete amplification of the amplifier is 400. The counting rats, of the
noise pulses at an effectiveness of the count of natural 04 equalling 6o-
65% is 0.5 pulses/min. An upper level discriminator is used to lower the
counting rate of the background determined by the cosmic and external radia-
tions in the given apparatus. Pig 1 is a blook-diagram of the described

apparatus and Fig 2 shows the principal circuit of coincidences. The tubes
of the apparatus are fed by stabilized sources of anode and incandescent
voltage, and the photomultipliers by a jX-9(VSw9)-type high-voltage source.
The positive pulses from the exits of two non-overloaded amplifiers are fed
to the inputs of the diode low-level disoriminatore (I - in Fig 2).

The limiting ( 7L 7@- ) diodes are used for eliminating the negative pulse
outputs fed to As, lot-level discriminator inputs. The selected photomulti-
plier should satisfy the following roquirem*ntsl 1) a high sensitivity of
the photocathode, 2) a high total sensitivity, 3) a low noise level, 4) sta-
bility over long periods of service, 5)j good temporary resolving power.
The adjuotment of the counter for the C-* spectrum is carried out according
to the 7-line of C8137. The discriminators of the lower level are installed
so that the number of the noise pulses at the output of the circuit of coin-
cidences would be equal to 0.5-1 pulses/min. The sample is counted in a
15.5 cm3-volume cuvette made of optic quartzite. The preparation of ethyl-
benzene and benzene from the carbon of the investigated material involves
the following chemical stepst 1) formsfion of C02'from the sample, 2) pro-
duction of strontium carbonate from C02 of the slable, 3) reduction of the

strontium carbonate to strontium carbide, 4) decomposition of strontium car-
bide, separation of acetylene from hydrogen and purification of acetylene,
5) synthesis of ethylbenzene from acetylene, 6) purification of ethylbenzene
and benzene. The samples to be measured are carbonates or organic substances
(coalp wood, peat, eto.). In both cases the carbon of the sample is separat-
ed out in the form of CO . The formation of CO 2 from the carbonate samples
in performed by the decol;osition of the sample with hydrochloric &aid. If
the investigated sample in an organic asterialp the formation of CO Is
carried out by heating the @am le in an oxygen flow. The single s;lthesis
of large amounts of acetylene Tup to 30 1) in carried out according to the
Susan method (R*f 4), the main advantage of which is said to be the almost
quantitative yield of acetylene (95%). The ayntheeis of othylbensene is
carried out according to the method of hydroalkylation of benzene with
ao5tylene in the presence of metallic Al, AM and hydrogen chloride (Ref
16 . The authors conducted a complete synthesis of benzene from the in-
vestigated material according to Reppe's method (Ref 13). The catalyst for
the synthesis of benzene by the given method is a compound of a mixed t

TITLEt The form in which atonis of radioactive elements exist
in minerals
PERIODICAL: Radtokhimlya, 1961, Vol.3, No.2, pp.'207-214
TEXTt The authors' study of tht I.L@achability of radioactive
elements from minerals has shown that their capillaries contain
atoms of isotopes of radt.um and other daughter radio-elementa
finding their way there through radioactive recoil. Uranium and
thorium, as well as various non--radioactive elements, are also
present. They are leached out of monazite and viikite by the
action of acid solutlon even when they do not dissolve. The8e
results could be explained only by the capillaries of these minerals
containing, in addition to daughter-element atoms, thoae of uranium,
thorium and the rare-earth elements. For a deeper understanding of
the form in which atoms of the elements exist in minerals, the
isotope ratios in the damaged parts of the mineral must be found.
The authors have developed various methods for finding that
proportion of atoms of elements which is located in capillaries and
damaged parts of minerals accessible to the leaching solution.

The form in which atoms ...
They have called the percentage of all the atoms of an isotope
present in a mineral which exist in capillaries and disturbances
Of its crystal lattice the "limiting leachabilitylt of this isotope.
Limiting leachability values show that capillaries contain enough
atoms to form an independent solid phass. The composition of the
compounds present there varies with the mineral. Different
minerals also have different capillary structures, which accounts
for the relative effects of neutral and acid leaching solutions
varying from mineral to mineral. Fig.2 shows the values of
limiting leachability for radium, uranium and thorium (curves 1,
2 and-3 respectively) as a function of acidity (0- 0.2 N hydrochloric
acid). This Indicates that for determinations of limiting
leachability acid solutions must be sufficiently acid to dissolve
fully the colloidal compounds in the capillaries and bring the atoms
of the elements present there into a form capable of exchange with
tons of the leaching solution. Solutions containing salta give
leachability values less than obtained with salt-free solutions of
the same acidity. There is no sharp boundary between the
capillary material, i.e. the fully disrupted lattice, and the
undamaged lattice. The maximum d-iipth frow which atoms can reach

show, using results published by Ye.P.Petryayev (Ref-13:
Radiokhimiya, 1, 1, 105 (1959)) that in the test sample of monazite
'the* radius of the sphere without capillaries or damaged parts in
its surface is 1.7 x 10- 4 'cm - The surface zone has the greatest
damage and supplies most atoms entering the capillaries. Unlike
atoms in capillaries, those in the damagL-d'parts of the lattice
can only be removed by more concentrated acid solutions. The
dynamic.leaching of minerals by strong solutions of acids is a
fruitful way of studying this part of the lattice. For this

TITLE: Extraction of Polonium in Various V&Iency States
PERIODICAL: Radiokhimiya, 1961, Vol.3, No-3, pp.261-271
TEXT., A brief review of the literature on the valency states of
polonium and its extraction is given. It is pointed out that the
valency state of polonium in the presence of reducing and oxidizing
agents remained uncertain. For this reason the authors
investigated the extraction of polonium from hydrochloric and
nitric acid containing media in the presence of oxidants-and
reducers, controlling its electrode potential of separation under
the same conditions, since the value of the electrode potential
is an objective indicator of the valency state of polonium. The
extraction of polonium with diethyl ether and a 10% solution of
tributylphosphate (TBPh) in benzene from solutions of
hydrochloric (0.1 to 11 M) and nitric (0.1 to 13 M) acids was studied.
The concentration of polonium was I to 2 x 10-121q. Sulphur
dioxide, hydrogen peroxide and hydrazine were used as reducing
agents and chlorine and potassium dichromate an oxidizing agents.

were shaken for 5 minutes. After settling, the phases were
separated and polonium was re-extracted from the organic phase with
equal volume of IN HCI. Aliquot portions for the measurements were
then taken from the aqueous phase and re-extracted. In the case
of extraction with diethyl ether, the latter was preliminarily
shaken with a non-active solution of the same composition as that
investigated since, at high acid concentrations, a considerable
increase in the volume of aqueous phase was observed which was
caused by dissolution in It of ether. From the ether phase,
polonium was re-extracted with 0.1 N hydrochloric acid. The
reduction was carried out by heating a given volume of the
solution to 60 to 70*C and bubbling sulphur dioxide for 15 min.
After standing for 0.5 to I hour, carbon dioxide was bubbled
through the solution. In nitric acid solutions the evolutions of
N02 and oxidation Of S02 to sulphate ion was observed. For
comparison, extraction of polonium from nitric acid solution
containing sulphuric acid was carried out. The reduction with
hydrazine and hydrogen peroxide was done-under the same conditions
adding them in the form of solutions. Chlorine was bubbled for
30 minutes through the solution which was heated to 60 to 700C.

Chromium was noticeably extracted'by the solvents used. On

described by D.M.Ziv and'G.S.Sinitayna (Ref.33: Tr.Rad.inst.,

electrode was used. An 0.01 M potassium permanganate solution in
2 M potassium chloride was used on the anode. A gold dine was
used an the cathode. The cell was polarized with a current from
an external source. Tn some cases (in 5 M HN03 and,HCI in the
presence of oxidants) the method of external electrolysis with-,
separation of cathodic and anodic space was used. All the
results quoted are the mean values of 2 -6 determinations. The
reproducibility of the extraction experiments was 12%. The
accuracy of determination of the electrode potentials was + 0.005 V,

given in the form of graphs. Electrode potentials T of polonium
in hydrochloric acid media are plotted in Fig.1 (A, imp/min vs V,V).
The dependence of the electrode potentials (9,V) on the
concentration of hydrochloric acid is plotted in Fig.2. Plots are
also included giving results on: extraction of polonium with
other and TBPh from hydrochloric acid solutions; electrode
potentials of polonium in nitric acid solutions; the dependence of
the electrode potential on the concentration of nitric acid; the
extraction with ether and TBPh from nitric acid solutions; the
dependence of the potential of anodic precipitation of polonium on
the concentration or nitric acid. On the basis of experimental
results it is concluded that: 1) In hydrochloric acid solutions in
the presence of hydrogen peroxide and sulphur dioxide,polonium is
reducad to the divalent state and In the presence of chlorine it
is oxidized to the hexavalent state. 2) From hydrochloric acid
media diethyl ether extracts only hexavalent polonium which is
present in the form of acidocomplexes. TBPh extracts polonium in
tetravalent state as well as in the reduced (divalent) state.
3) It was proved that in nitric acid media, reducing agents transfer

polonium into a lower valency state only up to a certain
concentration of nitric acid (1.5 to 2.5 M). At higher nitric
acid concentrations, oxidation of polonium to the hexavalent state
was observed during oxidizing-reducing processes taking place in
the solution. In nitric acid solutions, polonium is
disproportionate in all valency states. 4) It was found that
TBPh does not extract hexavalent polonium from nitric acid
solutions, removing only polonium in lower valency states.
5) It was established that from nitric acid media, diethylether
extracts only hexavalent polonium, present in an acidocomplex form
and does not extract polonium in reduced states. 6) It is shown
that oxidation of polonium with a mixture of nitric acid and
potassium dichromate, transfers- polonium into the state of (p002-)
which separates only on the anode and is not extracted with 4
ether or tributylphosphate. There are 9 figures and 35 references-:

TITLE. Adsorption of radioactive isotopes on non-ion-exchange

PERIODICAL., Radiokhimiya, 1961, Vol.3, No.1k, pp. 428-434
TEXT: So far most studies have been concerned with ion-
exchange and colloidal adsorption of radioactive isotopes. TO
establish the features of molecular adsorption of radioactive
isotopes it is most expedient to study a particular element under
conditions such that it may form uncharged compounds in solution.
In such a case it is possible to consider the molecular adsorption
as a distribution of neutral particles of electrolyte between
liquid and solid phases, and to compare the results with distribu-
tion of the element in extraction processes. Zirconium is
particularly suitable for such a study as in aqueous solution it
may form neutral complexes of type [Zr(OH)XAX-430 (Ref.5: B..A.Li-ster,
L.H. McDonald, J.Chem.Soc., 4315 (1952), where A is an anion.

The composition of the complexes depends on the composition of the
solution. In this way we may study adsorption an a function of the
solution composition and obtain information on the dependence of
adsorption on the state of the element in solution in order to
dad-ace the mechanism of molecular adsorption. The present work
,onsiders Zr adsorption on polytetrafluoroethylene (PTFE) from
hydrcchloric acid solutions, Zr desorption from PTFE surfaces with
tributyl phosphate (T5P), and the extraction of Zr into TBP.
It was nec@essary to take spcaial measures to ensure that tracer
zr95 and carrier zirconium are in the same state, e.g. as regards
hydrolysis. Adsorption was studied on polished PTFE discs 5.5 cm2
in area and 1.5 mm thick. Surface treatment with hot concentrated
mulphuric acid and water guaranteed rapid and complete desorption
of Zr95 while not affecting the adsorption properties. Zr95
a,:@tivity was measured on torsion counter with Al foil to absorb the
NO-51 @-radiation from the Nb formed in the course of the experiment.
The dependence of zirconium adsorption from 1.2 N HCl on zirconium
-on:entration may be expressed by a Freundlich equation of form

where G is the adsorption in g.atom Zr/cm2 and C is the
zirconium.concentration in g.atom/mf. For tracer concentrations
K = G/C is indep9ndent of C and is a function only of the state
of the Zr. With increasing Zr concentration the adsorption
approximates to that corresponding to a monolayer, which indicates
that adsorption is taking place over the whole surface and not on
individual parts. The temperature dependence of the adsorption
was studied in 10 N HCI to avoid hydrolytic effects which are also
temperature dependent. The value obtained for the heat of
adsorption on the hydrophobic PTFE surface is 2.2 t 0.2 kcal/mole,
which is usually characteristic for van der Waals adsorption ,
The dependence of Zr95 adsorption on HCI concentration may be
explained by the change in state of the Zr with changing H+ and Cl-
--oncentration. Calculations based on published complex formation
-f-enstants (Ref.12: A.S. Solovkin, ZhNKh, Vol.2, 3, 611 (1957))
show that the concentration of neutral zirconium species in very
high. It is found that the adsorption increases with the number
of hydroxyl groups in the neutral zirconium complex; this is
possibly due to the formation of hydrogen bonds between these

W-Uh- a change in state of the zirconium in solution. For
-extrar.-I-ion of Zr into TBP the salting-out effect for the cations
is in the reverse order: Ll > Na @1- K-> NH4 (in HC1). In this case
the effect is usually attributed to the different thermodynamic
activity of water in the salt solutions. For the same ionic
strength as the water activity increases, from Li to Cs, the
salting-out effect of the cation decreases in extraction. The
reverse seems to hold for the molecular adsorption of Zr on PTFE.
Total or partial reversal of this series is sometimes observed in
extraction proneases however, and is usually associated with
organic solution3 of high dielectric constant. Generally speaking,
the adsorption is not contrary to extraction theory and the main
points of similarity are: 1) in most cases of adsorption and
extra@.-tion there is an increase in uptake with increase i,@
--oncentration of s-4milar anions, and 2) the coefficients of

Var--fous suggezt-Jons are put forward to explain the effect of the
-nature of the neutral Balt cation on the zirconium adsorption. As
the adsorption increases with the degree of hydrolysis of the Zr
sollit'i-ons the effe@--t may be due to different degrees of hydrolysis
in solutions containing different alkali metal salts. other
suggestions are based on the different hydration of Lt* and Na+
compared with that of the other alkalf metals and the effect of
the ?z@axion on the extent of complex formation of Zr with chloride
ions .

TFXT.- From thexr study of polonium adsorption on cellulose and
glass from solution containing lanthanum nitrate and maintained in
the range of pH = I te 6, Tir3tiber and SchZinfeld concluded that the
presenc- of lanthanum nitrate has an appreciable effect on the
ndsorption of polonium, reducing it in some cases and increasing
n othe-j. The final conclugion was that at pH >., 1.5, the
pt-tonium adsorbed an such surfaces is in the 11"Orm of radiocolloids
and not as ions. The present authors disagree with the above

regard to the ac,cura-vy of Tauber and Scholinfeld's method of
determining the activity of polonium, It is suggested that for
the final elu,c@idation of the mechanism of polonium adsorption it
is neceasary to carry out more investigations of the effect of
various impurity elettrolytas and of the desorption of polonium

TITLE- Spectroscopic study of zirconium chloride solutions in
connection with the zirconium adsorption on fluoroplast-4
PERIODICAL- Doklady Akademii nauk SSSR, v. 137. no. 2, 1961, 356-358
TEXT: The authors deal with the problem of the distribution of Zr between
solution and nonionogenic surface (fluoroplast-4) under the influence
of the nature of the cation and the different degree of hydrolysis of
the Zr complexes. In a previo@j paper it-was shown thats 1) the
distribution coefficient of Zr between solution and fluoroplast-4
decreases with insrea8ing concentration of HC1; 2) at equal ionic
strength the adsorption of Zr increases in the presence of cations in
the order Li'@< H'+*
