Card 1/4
With reference to the palers (Refs 112,3,13,14)t it is stated
that an increase in the population of microbes in the zone of
convergence of nonuniform water masses is not only caused by the
high temperature gradient occurring at the intersection point
of warm and cold currents but also by the salt-content gradients
due to a mixing of waters from different oriGins. The observed
increase in the biomass of microbes in the zone of the so-called
jump of temperature may also serve as an example. As the temper-
ature gradients and the changes in the salt content are very
great in those places where anomalies occur in the quantitative
distribution of micro-organisms, an attempt is made here to
clarify the sensitivity of the bacteriological method for the
indication of "disturbancos" in hydrologically uniform water

maesesp in order to be able to use this method for the determina-
tion of cases with poor heterogeneity in the structure of sca or
ocean water. An investi(,ration of this kind could be -carried out
by the author (Ref 7) on the drifting scientific station "3P-3"
in the area of We north pole. This investigation, and the
investigations carried out by Butkovich (Itef 3) much more to tho
noutho in the Central Arctic, offered a possibility of ascertain-
ing that even fine features in the otratification of water
masses become evident with help of the mothod of determining
the anomalies in the quantitative distribution of micro-organisms.
Besides, the micro-organisms can aloo be used as hydrological
indicators in another direction. Thanks to the development of a
method for the direct microscopic investigation of the popula-
tion of microbes in scas and ocoann, micro-organisms have been
detected which cannot be j;ro-rn in the laboratory. Well re-
cognizable forms of microbes rere fouiLd which are peculiar to
certain compositions of water. Therefore, these micro-organinme
can serve as indicators for the origin of water masses. The in-

Phenomena in Seas and Oceans
Sea showed that-the whole hydrogen-sulphide zone of the Black
Sea, besides other micro-organioms, also producee some peculiar
thread-shaped kinds (Ref 10). They are the ori-ginal population
of the hydrogen-sulphide zone. They get into the higher layers
of the Black Sea by the water exchange between the hydrogen-
sulphide and the oxygen zonos. Due to a long-lasting vertical
circulation caused by the intense cooling of suiface waters, the
quantity of water coming from the hydrogen-sulphide zone with
its characteristic microbes in so large that the density of
the microbe population in depths of 125 and 150 m is some dozens
of times bigger in winter than in summer. How great ft imporbuioh of
the thread-shaped organiems as indicators for hydrological in-
ventigation iso can be seen from the fact that with their help
a "strange" water was ascertained in the hydrogen-oulphide zone
of the Black Sea. This water has another origin than the other
water masseo in this zone, which is also confirmed by observa-
Card 3/4 tions made by Kitkin and others. The causes are not clear yet.

ABSTRACTs The high-pressure tolerance of Psoudomonas sp, strain 8323, obtainod from
a depth of 1900 meters in the Black Sea, was determined experimentally. Some oul
turos in a modified Rana madi= and held in special glass flasks were placed in s;0011
cylinders filled with water and were subjected to various hydrostatic pressures for
2-3 days at 28-290; the rest were kept under the same conditions except at atmoo-
pheric pressures With the aid of a Goryayev camera and an FM-57 nopholomatero the
concentration and number of bacteria were determined. Results indicated that at
pressures between 25 and 400 atmospheres bacterial growth exceeded growth a-
phoria preasiwas At 600 atmospheres a repression of growth and reproduction

TITLE: Reaction of Cobalt Salts with Potassium Xanthates
(Vzaimode7stviye soley kobal'ta B ksantogenatom kaliya)
PERIODICAL: Tsvetnyye Metally, 1958, vr 10, PP 53 - 5 (USSR)
ABSTRACT: The authors comment on the views of I.A. Kakovskiy
(Tsvetnyye Metally, 1958, Nr ?) on the processes occurring
during the removal of cobalt from zinc-electrolysis
solutions with the aid of potassium xanthate. They maintain
that the method used by Kakovskiy to study the compusition
and properties of xanthates of various metals is not
applicable to cobalt xanthate; their more careful
repetition of Kakovskiy's experiments showed (table) that
the reaction of soluble cobalt salts with potassium
xanthate is not the simple exchange assumed by Kakovskiy.
They indicate that this author contradicted himself and
based his conclusions on erroneous experime7ntation which
also distorted his thermo-dynamic treatment of the
subject. The authors refer to their own work (Refs 4, 9)
which showed that copper can advantageously be replaced
by their oxidising agents, in particular, hydrogen per-
Card 1/2 oxide as used at the Zlektrotsink Works; they do not

TITLE: On Cobalt Xanthogenate (0 ksantogenate koballta)
PERIODICAL: Zhurnal neorganicheskoy khimii, 1959, Vol 4, Nr 2l
PP 472-477 (USSR)
ABSTRACT: 'The Interaotion of potassium xanthogenate with cobalt sulfate
in aqueous solutions, depending on the pH of the solution, was
investigated. The transformation was determined by physloo-
chemical and chemical analyses. Upon the interaction in a
slightly alkaline medium a precipitate is formed which can be
extracted by benzene. The formula of cobalt xanthogenate, re-
crystallized from'benzene, is Co(C 2H5ocs 2)3 . After extraction
of cobalt xanthogenate a black residue remains which is in-
soluble in benzene and other organic solvents. The analysis
of the residue showed' -34% cobalt and -18% sulfur. The black
residue is a mixture of several compounds which are formed upon
the interaction of cobalt ions with decomposition products of
potassium xanthogenate. The interaction of the aqueous solutions

exchange reaction but is accompanied by secondary reactions.
The optical density of the system cobalt sulfate - potassium
xanthogenate was determined. At the same time the formation
of the oompound:Co(C 2H5ocs 2)3 was determined* Xanthogenate
decomposes quickly in acid solutions, at the name time the
optical density decreases without the formation of a maximum
of the curve composition - optical density. The decomposition
velocity of xanthogenate rises with the increase of the con-
centration of the acid and the increase of the duration of the
interaction of the components. The results show that physico-
chemical analyses of the system potassium-xanthogenate-cobalt
salts in aqueous solutions give no satisfactory results because
of secondary reactions, There are 3 figures, 2 tables, and
15 references, 8 of which are Soviet.

TEXT: The distribution coefficients of nitrates of lanthanum,neodymium,

tration and the concentration of rare earths, and compared. Extractions
were carried out at 20-210C in a shaking funnel for 25-30 minutes. Carbon
tetrachloride was used as solvent for di- and tributyl phosphate. The
rare earth content in the aqueous and organic phases was ditermPed

traction with dibutyl phosphate when the nitric acid concentration and the
concentration of nitrates of rare earths increased in the aqueous phase,

whereas in the extraction with tributyl phosphate, when the concentration
of nitrates of rare earths increased, the distribution coefficients were
found to increase. Separation of rare earths at low acidity of the solu-
tion is easier when tributyl phosphate is used. Tables give a good survey
of the results obtained. Table I gives the results of the nitrate extrac-
tions of some rare earths and of yttrium with one-molar solutions of tri-
butyl phosphate and n-dibutyl phosphate in CCI 4 in dependence on the ni-
tric acid concentration. Tables 2 and 3 show the distribution coefficients
of nitrates of rare earths In solutions of tributyl phosphate and n-di- V/

thanidene nitrates Ln(NO 3) To compare the efficiency of extractions,
Table 4 shows the results 9f* nitrate extractions of some rare earths with

TITLE: interaction of some rare earths with d1butyl phosphate and
their separation by extraction
PERIODICAL: Akademiya nauk SSSR. Doklady, v. 138, no. 4, 1961, 846-849
TEXT: The authors studied the complexes formed in the interaction of ions
of rare earths with acid dibutyl phosphate (C 4H90)2HP02 (HDBP), determined
their instability constants, and separated some pairs of rare earths by
this method. On the basis of published data they concluded that dialkyl
phosphates (R2HPO 4XR - alkyl radical), particularly HDBP, are superior to
tributyl phosphate for such a separation. The distribution coefficients
(q M) for extraction with HDBP decrease with increasing concentration of
nitrates of rare earths. With the use of.R2HPO 4' the separation coefficient
of adjacent lanthanides varies between 1.95 (light lanthanides) and 2.6
(heavy ones), whereas it lies between 1 and 2 with tributyl phosphate.

the interaction Yb(DBP) + n(RDBP YbTH(DBP (2). They calculated

the equilibrium constant of the complex formation and determined the number

This suggests a strong dissociation of +;he complexes of rare earths with
DBF. Considering this, the authors derive the equation for the equilibrium
constant: logK - log q - 3 log fA_1- 3 log fHA" (7). Besides, they
determined the values Of log-K for-the complexes of praseodymium. neo-
dymium, and ytterbium of the type M ~_H DBP) 2-.3- they were 15.0, 15.3, and
18.5, respectively. The great difference in the stability of complexes
between yttrium and cerium ele 'ments in the extraction with HDBP may be
utilized for their separation. The separation coefficients depend on the
position of elements in the lanthanide group, the cohtent of M103 in the
aqueous phase, the HDBP concentration in the non-aqueous phase, and the
quantitative ratio of the elements to be separated In their mixture. The
coefficient varies between 1.9 and 2-4 for the pair Nd- Ho. In the re-
extraction of elements from'the non-aqueoue phase, an additional separation
may be attained by xitilizing the different atability of complexes with
HDBP. Thus, cerium elements are precipitated by oxalic acid, and
additionally separated from the.yttrium element.s. The latter can be
precipitated by NOR from the solution in RDBP. There are 2 tables and
