carbanate. This synthetic sorbent adsorbed selectively the
copper-ions from solutions which are close to natural waterm
with respect to their composition and which contain a number
of other tone (Table 1). Under these conditions, the alumo-
cilica-gels lost their capacity of adsorbing copper, even
if and when the concentration of perturbing ions was much
lower.The effect of this adsorbent is !tpparently explained
by a prenent amino-group an well as by a certain capacity
of co;f.er to form ammonicates. This adsorbent stands a
multiple trent=ent with I n -HCl (for the purpose of copper-
deaorption). Purther the adsorption capacities of alumosilica-
tjols and of the nilica-gel after a treatment with ammonium
h.Tdromida'are discussed. The latter was washed out until a PH
0 was attained. The dependence of the adsorption of
copper by the produced adsorbent on the concentration of
copper in the solution was determined by the method of sin-

ABSTRACT: The authors propose the use of ' sinking- particles' method, which is
convenient in field work, instead of the ion-exchange column The
completeness of extraction of microcomponents depends upon the
size of the resin particles. the amount of resin used, and the concen-
tration of cations. The best extraction of Cu2+ at a concentration of
80 -y /liter is attained witi, 10 grams of resin of 100- 150 p particle
sine, The joint extraction of Cu, Zn, and Pb from solutions produced
good results. Fe did not imp4-de the determination The second

TEXT: The thormo-chemical method of determining oxygen
concentration In gases in based on measuring the temperature of the
catalytic reaction of oxidation on an active catalyst in the gas
stream. A recent automatic instrument of this kind is gas
analyser type TXV-5 (TKhG-5) (Ref.2: Instruments developed by the
experimental d0sign office for Automatics Branch of Technical
Information OfCice or GIAP, Moscow, 1953, P-11i Ref.3- Thermo-
chemical Us Axialyzer type MG-5. All-Union Industrial
Exhibition, MK1%F USSR, Moscow, 1956). This instrument covers the
range 0 to 1% 02 and is used to determine oxygen in hydrogen or
vice versa.. In studying the flameless combustion of hydrogen on a
Pt/Pt-ft thermocouple, the authors concluded that it was possible
to us a a simple type of burner for the continuous determination of
Card 1/1

S/153/60/003/003/034/036/xx
A thermo-chemical gas analyser S194/E484
oxygen in gas mixtures. The operating principle is that flameless
combustion of' hydrogen, initiated by heating, occurs on the
junction of a catalytically actiye thermocouple located
immediately above a tube which delivers hydrogen into a vessel
containing an atmosphere of the gas, which contains oxygen, to be
analysed. The couple e.m,f. is proportional to the oxygen
concentration. As the process of flameless combustion is usually
unstable at oxygen contents below 10%. the object of the present
work was to make equipment of this kind work at concentrations
below 10% by raising the temperature of the reaction. The
original experimental burner I.* first described. The incoming
hydrogen and Sgts in the vessel are heated, the cold 3unction of the
catalytic thermocouple (Pt/Pt-1r) Is in the ambient gas. The
ambient temperature of the gas, in which the catalytic thermocouple
is located, is measured by a chromel-alumel thermocouple.. The
bulb surrounding the burner Is thermally insulated, In the
absence of combustion, the thermocouple e.m.f, was practically zero.
Flamelemn combustion occurred spontaneously at a temperaturt- of
150*C. With i1i" gas heated to 250- 300%, stable flamele's
combustion occlArs wlth~ oxygen concentration down to some tenths

of 1%, The test results obtained with this experimental model a:-c-
described,. On the basis of these results a prototype automAtI.-
gas analyser for oxygen was developed and tested, The burner head
is illustrated diagrammatically in Fig.5, To reduce heat losses
the burner head is contained in a double walled dewar flask 4.
The Sas containing oxygen is delivered at a steady rate through the
tube 10 and hydregen in delivered also at a steady rate through the
tube 8 both are heated by the heating coil 9 to a
temperature of 250 to 3000C, The catalytic Pt/Pt-Ir thermocouple
4 Is located 2 to 3 in above the top of the hydrogen delivery tube,
The cold junction of the catalytic couple 6 is outside of and
2 to 3 min below the top of the hydrogen delivery tube, The
temperature at this place is measured by a chromel-alumel couple 5
With this arrmngement when spontaneous ignition has occurred and
flamelas4 combustion is taking place the thermocouple e,m,f, is
proportional to the oxygen concentration, The layout of the
prototypu equipment to described and operating instructions are
given. Pig,,fl ohows a curve of the catnlytic thermocouple e.m,f,

The oxygen contentration with the various curves is 1 - 1,8%
2 - 5%, 3 - 7,.3%, 4 -- 10%, It will be seen that with an oxygen
zoncentration (if 1,8%, stable flameless combustion occurs with a
hydrogen delivory rate of 1.5 ml/min, Grapbi of this kind are
used to dotermxne the optimum rate of hydrogen delivery and then
for set conditions the reading of a millivolt meter connected to the
-'atalytxc therntocouple can be calibrated in oxygen content, Fig,9

oxygen content for the following rates of hydrogen flow.
Curve 1, 5 MI/Min, curve 2, 10 ml/min, curve 3, 15 ml/min,
Practical recommendations are made about operating conditions.
In determIning the oxygen concentration of a mixture of oxygen and
nitrogen in the range or i to 10% oxygen, the results agreed with
those obtained on a STH (VTI) type gas analyser (which has an
error of - 0,0) to within + 0.3 to 0.5%. I.e. 5% of maximum scale
value; Yhe lower limit of-oxygen concentration to defle:t the
meter was 0.2%, The instrument reacted to changeb of gas
concentration mfter about 20 seconds, The equipment is simple and
can be readily adapted to automatic measurement of oxygen

change of 1% oxygen concentration is 0.4 to 0.9 mv. With further
development, the sensitivity and accuracy will probably be
improved, the method can be used to determine oxygen In a mixture

ABST.:UCT: A t-3chnlq-ao applicable to hydrochomical -orosx)ecting is Dronosod for co-.-
tantalum from dilute solutions and naturs,11 waters. It involves conreci-
pita-.ion of tantalum with aa&dmn sulfide, calcium carbonate, and ferric hy6roxido
collectors. The Ini'luence of a number of factors on this coprecipitation was studied.
T
ihe conricipitationk was increased by introducing third cormonents (0.1 Mg.-eq of Iron
or aluminum salt), and varied with the initial DH of the solution in the caso of CdS
in the nrosence of iron salts. ChakTes in the time of contact between the prociDi-
'.&to and the solutlon, the presence of extraneous electrolytes (coprecipitation in
sea wzte-~, a chanMa in the ionic strength of the solution and in temoerature from 44
to +700, azd aging of the colloctor with the trace element for 14 days had no effect

that the c*procipdtation involves the formation of tantalate-type compounds in the

A3STRACT: 'Me kinetits of oxyg-in quenching of Trypaflavine supported on silica,
silica containinq 0.0-9% A13+ ions, and silica containing 1-4% e ions was studied.
Foreign ions (ILl ' iknd e) were introduced to silica by ion-exchange technique.
After degassing in vacuo at 18011C, various silica supports were contacted with
Trypaflavinf- solution (10 ml of 5-10-5 molar solution per I g support), decanted,
washed with water, und dehydrated to various degrees by holding in vacuo for 2-40
hours at 20-5600C. During quenching experiments, the oxygen pressure was varied

from 7.0x10-6 to 9.6x1O-1 mm Hg. It was found that oxygen quenching of phosphor
supported on pure diehydrated silica does not conform to the Stern-Volmer rule. It
was also found that the shape of the quenching curve is a function of the degree of
dehydration of the silica surface. The phosphorescence sensitivity of supported
phosphor was found to depend upon the nature of functional groups present on the
s1port's surface. Tor phosphors supported on either'highly dehydrated silica or
Al I containing silica, the shape of the oxygen quenching curves approaches that of
the theoretical curve. It is postulated that the mechanism of phosphorescence of
the adsorbed molecules depends upon the nature of the surface adsorption sites. An
empirical expression is proposed for the quantitative treatment of phosphorescence
of supported Tryp&Elavine. The kinetic data are graphed and tabulated. Orig. art.
