SEPARATION OF URANIUM FROM BISMUTH USING TRIS(2-ETHYLHEXYL)PHOSPHINE OXIDE. INCREASE IN SELECTIVITY WITH 1,2-CYCLOHEXYLENE DINITRILO TETRAACETIC ACID
Experiments designed to find a quick and straightforward method for the separation of trace amounts of uranium from large excess of bismuth, allowing for a subsequent determination of the former, are described. It has been shown that the possibllity of such separations using tris(2ethylhexyl)phosphine oxide can be enhanced if another masking agent is introduced into the system. Extraction with tris(2-ethylhexyl)phosphine oxide in the presence of 1,2-cyclohexylene dinitrilotetraacetic acid followed by ultraviolet absorption has been successfully uillized to develop a method for the separation of uranium from 20,000fold excess of bismuth.
