Abstract

It is possible to extract Sb(V), even in traces, nearly completely from 6M HCl by 2,3,5-Triphenyltetrazoliumchloride (TTC). The molar ratio of the ion associate in the organic phase is found to be 1∶1. Graphic evaluation of radiometric measurements using125Sb as tracer give the following results: extraction constant Kex=1.65·104, distribution constant KD=19.95, stability constant of the ion associate β=0.83·103.
