TITLE; Chromatographic Separation of Zirconium and Hafnium
PERIODICAL: Zhurnal neorganicheskoy khimii, 1960, Vol. 5v No. 12,
pp. 2844-2847
TEXT: A new method of separating zirconium and hafnium by means of the
RY -2 (KU-2) cationite was developed. A solution of 0.025 mole citric
acid and I mole perchloric acid, or 1 mole nitric acid, was used as desor-
bent. The rate of desorption is 0-5 - 0.6 ml/min-cm2. Zirconium and haf-
nium. were radiometrically analyzed in the extracts with the itiotopes
Zr95 and Hf 181
(~ Figs I shows the curves for the chromatographic distribu--
tion of Zr95 Nb9 ) and Hf. It was found that with an increased loading
of the cationits the value V max rises, and the ratio
Vmax Hf/V max Zr decreases. This effect is explained by the formation of
polynualear zirconium complexes, and the effectof the large zirconium

of zirconium separation from hafnium was investigated, and it was found
that when H SO is used as desorbent separation is easier than when

ABSTRACT: The.authors studied the condition of zirconium in aqueous solutions
'of Zr0C1 sub-2 -8H sub 2 0 by potentiometric, cryoseopic, and electric conductivity
methods, and by measuring the diffusion rate. Purpose of study was to obtain in-
formation concerning hydrolysis and degree of polymerization of this compound.
ZrOC1 sub 2 OH sub 2 0., thrice recrystallized from a co:=ercial chloride solution,.
was used for the study. The composition of the compound corresponded precisely to
the forrv.1a. The solution3 to be tested were,prepared by disnolving a wei0ied por-
tion of the salt, in distilled vs;ter which was chilled to 3-4 The solutions
-were kept at this temperature for 24- hours. In all cases, each experinent was
-d the activity of hydrochloric
repeated no less than two, times. Authors determine 4
acid in zirconium oxychloride solutions at 0.2, 10, and 25* in concentration
ranges of 0-006-0-38 mol/kl. The drops in the freezing points of the zirconium
o3Wchloride solutions were measured in relation to salt cc-ncentration

of Zr:)C1 sub 2,8H BuS 2 0, HfOC1 sub 2.8H sub 2 0, and ThCl-sub 4 were determined.
The electrical conductivity of zi-rconium Mchloride solutions was measured at

ABSTRACT: While inorganic complexes of Zr4+ and Hf4+ andtheir
equilibrium and stability constants are known, nothing is known
.,about their complexes with such wide spread substance as comp e-
f4+
xones. Therefore the authors undertook a study of Zrz+ and H
complex forination with triacatonitrile (TAN) in a strongly acidic
medium and determined the compcsitions and the equilibriumvconstants
of complex forming. In the te6ts, the ion exchange method was ap-
pl%, a~g catigy exchange resin KU-2 was used. Metal concentration
(Zr +Nb HE was 10-6 molll ano acidity.-I-2 molll HC104' TAN
concentration,varied between 0.4-10-'+ and 23.10-4 mol/j; and its

ABSTRACT: Despite the growing Interest In the chemistry of zirconium and hafnium, few
studies have been performed on their complexing with organic and Inorganic substances.
There are only few determinations of the composition and stability constants of complex

ABSTRACTI The XPR spectrum of the Iodide cc4W1= of Yb(V) was studied with an
M-1301 specti ter at -9000 No, In all caseep ZPR signals with g z 2.058:ko.004
were obtained. A study of the Influence of various methods of preparation of the
complexy concentration dependence and formation of aired coftlexes (HI + HClp HI +
HBO showed that the line with g a 2.058 belongs indeed to the iodide complex of
MoJV)q which has the Nam composition and structure an other halide complexes of
No Wo Thust the g factor of the iodide complex is greater than that of tho free
electron, this being very urmsual for ions with a single d electron. An attempt was
made to obtain mom detailed information on g factors by studying the XPR spectra of
the iodide complex of Mo(Y) at 776K; the values gj w 2.23840.005 and gcl 1.97 were
thus obtain*d,. By using the average value of the g factorp g, and the relation

TEM This paper describes the operation of a cathode switch
detector that can be used in the pulse measuring technique, in phase sen-
sitive circuits, or as a peak detector for measuring short pulses. The
operation of the cathode detector commutated by rectangular voltage pul-
ses coherent with the voltage acting on the control grid is described
and following expressions denoted (see Fig. I and Fig. 2) 1

tical example is worked out with known values of parameterB; The circuit
of the cathode detector is very selective and, therefore, it can be uti-
lized in an equipment measuring magnitudes with correspondingly high'.ioi-
as to signal ratio. The circuit described in this paper forma the basis
of an instrument designed -to measure magnetic characteristics of materials.
Thin instrument is now being subjected to laboratory tests. There are 5
figures and 5 Soviet-bloc references.
