TITLE: A Study of the Conditions for the Quantitative Separation of
Antimony From Solutions With the Aid of Di anti pyrilmethane
(Izucheniye usloviy kolichestvennogo vydeleniya surlmy iz

PERIODICAL: Uch. zap. Kazansk. un-ta. 1957, Vol 117, Nr 2, pp 184-187
ABSTRACT: Experiments were conducted with standard solutions of Sb
with additions of a radioactive isotope. After creating a def-
inite concentration of the halide, Sb is precipitated with an
acid alcohol-water solutici-n~'bf.~,diant:ipyrilmethane (D). The
most corr~plete precipitation occurs in the presence of I
(to 5' 10-"g/ml). The precipitate is dissolved in an alcoholic
solution of HCI (IN HCI and 500/o of alcohol) and Sb is deter-
mined polari g ra phic ally. The excess of D has no effect on the
height of the step. The error of the determination of Sb is
