TITLE: The extraction of variou& metal nitrates with mixed solvents
PERIODICAL: Radiokhimiya, v. 2, no. 5, 1960t 531 - 536
TEXT. The present article offers the results obtained in a study
of the extraction of micro-quantities of metal nitrates of various valency;
cerium, zirconium, niobium and ruthenium. The study was carried out on
the extraction of trivalent cerium nitrates, and the other metal nitrates
using mixtures of simple oxygen-containing solvents, and on the phenomenon
of non-addivity, i.e., the extraction of the nitrates exceeding that of
the computed value of extraction, estimated from the assumption of inde-
pendence of the extraction by each component of the mixture with respect
to the presence of the other. The following preparations were used in the
experiments: Ce144, Zr95, IM95, Ru 1o6 , of the "non-carrier" grading. Two
mixtures were used as the extracting agents, which were extreme with re-
spect to the extraction of the nitric acid and uranyl nitrate, i.e., ex-

tracting these better than pure solvents individually, dibutyl ether-ppl-
-dichlorodiethyl ether, (chlorex) and diethyl ether-acetophenone. Figurc-s
1 - 7 show the results of the experiments, indicating that the investi-
gated mixtures are really non-additive with respect to the extraction of
all the mentioned elements, and the values of deviation from the addivity
become rather high. The extremeness, however, is only present for the
solvent mixtures which extract the given nitrate in the pure form, to about
an equal extent. The data showed that the non-addivity (formation of mixed
solvates) is characteristid not only for the extraction of the given ele-
ment by the mixtures of various oxygen-containing solvents (Ref. 1: V. LT.
Vdovenko, A. S. Krivokhatskiy, ZhITKh, 5, 494, 1960), but also for the ex-
tracting of various elements by one mixture, proving the gener *ality of the
phenomenon. The possibility of increasing the degree of separation of the
elements by selection of the corresponding composition of the extracting
agent, as a result of the aiffarence in the shapes of the curves of extrac-
tion of the various elements is shown. There are I table and 7 figures,

as a function of time (min). The curves tend toward saturatLon. The ef.-
feet of paramagnetism of free radioals should vanish because of their
short, lifetime, immediately after illumination is stopped. The authors,
howeverg obser1red an effe--t persisting for hours. Thus, the affect is
caused, not by free racl-i,.--als, but by prcdusts formed iinder the"LT action.
St.;Irring of irradiated H20 led to a decrease of signals proportional to
the intensity of mechanir,,a? action, under the evolution of oxygen. The

TITLE: Proton relaxation in aqueous solutions of diamagnetic salts
PERIODICAL: Zhurnal strukturnoy khImli, v. 2, no., 1, 1961, 64-65
TEXT: It is of special interest to study solutions of uranyl salts, which
the authors have already previously described (Ref. 1: V. M. Vdovenko,
V. A. Shcherbakov,. Zh., strukt. khimii, 1, no,. 1, 28,(1960)). Such a studyis
of importance not only to gather informaTion on the nature of this ion and
its hydrates but also with respect to another question the authors have been
dealing with earlier The method of the present work hardly differs frc
one they have described in the first communication of this series. UO 4 "CLZ
prepared by precipitating It in the cold with hydrogen peroxide from aqueous
solutions of uranyl nitrite. After that, UO4 was dissolved in the correspcnd-
ing solution. By working with a certain excess of acid, hydrolysis was
excluded (the PH of the solution was about 0),. The concentration was con-
trolled manganometrically. Only in the case of hydrochloric solutions, the

gravimetric method was applied, The experimental results are given in the
Figure and in the Table The ratios T'/To were calculated by a method des-

cribed in communication II. As may be seen from the Figure, the influence
of the uranyl ion upon the time of proton relaxation (I/Tj) depends on the
nature of the anion, This dependence is confirmed by the values of the
molar relaxation shifthM,and above all, by the values for Ti/TO (Table). 9he

latter values are about the same for hydrochloric and nitric solutions, but
are much higher for perchloric and sulfuric solutions. The correlation
between shift and ratio ri/,rO for the uranyl Ion on one hand and the ionic
C 0
radii on the other, is of special interest (cf. Table)~, The most important
conclusion drawn by tile authors is that the degree of covalence of the bond
U - OH 2 does not remain constant, but depends on the nature of the anion in
the solution.. If one considers the anion capability of complex formation
with uranyl then the explanation of the above effect as being due to the
formation of covalent bonds ion-anion is rather unconvincing, especially,
since the stability of the complexes increases in the order
