Abstract: It is ohm that the Kolthoff equation (H. C. Jutzy and L 14. Kolt-
hoff, J. Amer. Chem. Soc.., 1937, ~Z 916), vhich gives the distribu-
tion of 2 4ctrolytes betveen the solution and the residue at equal
concentrat~:Mns of the components, is identical with an equation which
had been deduce& earlier (Ratner, Tr. Goo. radievogo in-ta, 1937,
Vol 3) and which gives a theoretical formulation of Khlopin's law.
In the opinion of the author, it may be considered as established that

ABSTRACT: Conditions have been found which secure over 90% co-
precipitation of traces of metals forming slightly
soluble hydroxides with the hydroxides of other metals
during concentration by precipitation of the collector-
substance by excess reagent and by partial precipitation
of the macro-component as hydroxide. For the first
method of concentration this requires a pH value for the
solution greater than that for the precipitation of the
hydroxide of the metal being co-precipitated; the
attainment of the solubility produet of its hydroxide
is not then of prime y importance. Nor is the

ptesence of other electrolytes, differences in
properties of the hydroxides of the metal being
concentrated and of the collector, temperature, the
duration of ageing the precipitate after co-preoipitation
or the order in which the reagents are added. For
concentration by the second method a definite, empirical
ratio between the macro-and micro-component concentrations
must be attained; otherwise the micro-component
distributes itself between the solution and the precipitate
in the normal way. There are 10 tables and 16 referenees,
of which 13 are Slavic.

ABSTRACT: An examination was made of the phenomenon of coprecipitation (C)
of Cu (N.i) with basic salts (hydroxides) of Fe and Al from dilute solu-
tions and also of adsorption (A) of Cu (Ag) on Mn02. C was performed
from bicarbonate solutions while Cu was precipitated from acetate
solutions under -conditions in which 30 - 700/o of the metal would be
included in the precipitate. The author notes that extraneous electro-
lytes have little effect on Cu, whereas an increase of the buffer mix-
ture brings about a decrease of C. It is assumed that Cu (Ni) is ab-
sorbed by the precipitate during G in,the form of hydrolysis products

the C process.* It is shown that the A of Cu and Ni salts on Fe(OH)3 has a hydro-
lytic character and that the C of Cu (Ni) increases with the decrease of the stabil-
ity of the compound binding them in the *solution. If Fe(OH)3 contains an adsorbed
or a coprecipitated electrolyte, the absorption of another e1qctrolyte from the solu-
tion can occur by means of ion exchange. Upon a decrease'in the sirent),th of the
solution the A of Cu by the MNO? precipitate increases, whereas the A of Ag remains
unchanged. It is concluded that the distribution of Cu(Ni) admixtures between the
solution and the precipitate of Fe(OH)3[ AI(OH)3] during G and A follows different,
laws which is an indication of*the complexity of the mechanics of the absorption of
electrolytes by metallic hydroxides. The process of absorption of metals by Fe
and Al hydroxides (basic salts) in the form of hydrolysis products predominates,
Therefore, the effectiveness of C of metals which form dissolution- resistant hy-
droxides can be affected by regulating the extent of the hydrolysis of the compounds
of these metals during the C with metaflic hydroxides. Metallic ions are adsorbed
on the MnO2 hydrate by means of exchange with water ions.

ABSTRACT: The possibility of the concentration of arsenic and phosphorus
in depositions from solutions of zinc and ~ma-nessiura salts was
shown experimentally. It was found that th-~, carryin--down of
microcomponents in the deposition amounts to almost 90~% By
means of this method it 12 1)osniblo to concentratearsenic and
phosphorus from highly diluted solutions (dilution 1:109). The
carryin-flown of the microcornponconts arsenic and phosphorus
remains the same when instead of a partial precipitation of the
zinc and ma.-nesium salts of the sample investigated newly pre-
cipitated zinc or mngncsium o~:idc is added. The mechmism of
the carrying-down of thane arsenate and phonphate microcomponentn
is one of adsorption. Th(,re are 2 tables and 1 reference,

PERIODICAL: Zavodskaya laboratoriya, v. 29, no. 5o 1963, PP 522-523
n..XT: When.cadmilm hydroxide is partially precipitated from a solution of,
cadmium sulfate the zinc present in the solution as an Impurity is distributed
between the solution and precipitate-. The Zn can be quantitatively extracted
with CC14 if the Cd is in the form of the nitrate or sulfate and a considerable
excess of iodide is added to form complexes with the Cd ions. Thiourea masks the
influence of other heavy metals mucb more effectively than thlosulfate., ordinar-
ily used. Previous investigations showed that traces of zinc are quantitatively
co-precipitated with CdS from solutions containing metals not precipitated by H2S
at pH 2. This was used as the basis of a method of determining ultrasmall
(0-5 - 2 micrograms/gram) impurities:of Zn in such salts (Cd. Al,, Cr, Fe, Ma and
Vi sulfates wereused). The article has 1 table.

ABSTRACT: Clarification of mechanisms by which acid substances react with an adsorbent
surface was sought through an analysis of infrared absorption spectra for the adsorption of
hydrogen chloride on amino organosilica and of methacrylic acid on an amino organoaerosil.
A supplementary analysis concerned adsorption of methacrylic acid7on the named aerosil from
an aqueous solution. Another aspect of the study involved reinforcement of the carboxyl-con-
taining polymer SKS 30-1 by dispersion type arnino organosilicic fillers. Results indicate that
Aemisorption occurs, with an accompanying formation of chemical compounds on the adsor-
bent surface. Amino and vinylaTnino derivatives of silica white A, used as fillers, reinforced
the carbo.-WI -containing polymer through interaction of functional groups and the accompanying

ABSTRACT: The problem has been investigated by a number of authors
(Refs. 1-6) but it was felt that an additional investigation
was justified. The experiments were carried out on a tungsten
plug, having a porosity of 0.2 (see Fig. 2a)i the velocity of
the strontium vapour diffusion was compared with the corres-
onding free flow of the strontium vapour from a "black body"
see Fig. 26). In both cases, the disptnser contained the same
~
mixture (Ba, Sr)CO which was marked by the radiolative isotope
89 3 e
Sr and a quantity of tantalum powder w.hLelr!~w"/in a tantalum
ampule having a siare-like cover. The experiments were carried
out in a special tube (see Fig. 3) which contained a fixed
cathode and a system of seven movable collectors. The presence
of the collectors permitted the measurement of the velocity
of the diffusion as a function of temperature. The measuremgnts
Cardl/2 were carried out over a temperature range of 1 350 to 1 550 K.

Diffusion of the Strontium Va ours through the Plug of a Porous

The results are illustrated in Fig. 4. This shows the pressure
of the strontium va-Dours as a function of temperature to a
semi-logarithmic scale. The Curves 2 and 3 refer-.,to the
pressure above the surface of the cathode, while the Curve 1
relates to thq~,pressure in the chamber of the cathode. From
the above, it is concluded that diffusion of the strontium
vapours through a fine plug,having a porosity of 0.2,is mainly
due to the migration mechanism (over the investigated range
of temperatures). The jump in the vapour pressure between the
surface and the chamber ranges from 280 to 1 800 for the
investigated temperatures. It was also found by interpolation
that for the normal operating temperature of 1 000 'C, this
jump would be equal to 100.
The author expresses his gratitude to Corresponding Member of
the Ac.Sc. Ukrainian SSR N.D. Morgulis for his interest and

TITLEs Some Specific Features of the Partial Adsorption of Residual
Gas Components at Very High Vacuwa
PERIODICALt Doklady Akademii nauk SSSR, 1959, Vol 128, Nr 51 PP 930-932 (USSIR)
ABSTRACT: In the present paper the authors investigate the properties of
a "natural" mixture of residual gases generally present in
electronic devices at high vacuum. For this investigation the
authors use a mass spectrometric device intended for investi-
gations in the field of high-vacuum processes. The inside of
the mass spectrometric analyzer tube employed was fitted with
a long tungsten band. This tube consisted wholly of glass and
was soldered. The pressure of the rosidual gases was
p - 1.10-8 torr. The tungsten band served as the basis on
whose surface the components of the residual gases investigated
were adsorbed. A schematic representation of the mass spectrum
of these gases is given in a figure. The present problem was
investigated by the well-known "flash" method. The relative

may be determined from data given in the above-mentioned
figure. This degree of adsorption is proportional to the mean

denotes the total amount of gas adsorbed within the given time.
The following interesting conclusion is arrived at:
k (He) = 0' i (H (N ). In order to obtain more exact

data on the specific features of adsorption of each gas
component in the mixture, the partial adsorption rates were
determined by measuring the eependence of the quantity M M
on the time t of previous adsorption exposure. This
dependence is represented in a diagram for the 2 main oomponants
H and N For comparison, the dependence AI is shmvn for

Some Specific Features of the Partial Adsorption of SOV/20-128-5-18/67

can be investigated more closely by means of the temperature
variation with respect to time. In doing so, the authors
observed the polyphase nature of the adsorbed states of E2
and N2 on tungster4 which complicateo this phenomenon even
more. The third diagram gives the characteristics of
partial dependence on adsorption of the "pumping out" of the
gas components 112 and N2 from the mixture of residual gases,
after the tungsten band had been freed from these components
by "flashing" at high temperatures and then cooled. The
curves shown in figure 2 are qualitative representations of
the integrals of the curves given in figure 3. Investigations
of this problem are being continued. There are 3 fi,-xres and
2 referencesp 1 of which is Boviet.
