Radiochemistry Aims and scope

Abstract

Coprecipitation of 60Co microamounts from aqueous solutions with sulfides of d elements (Cu2+, Ni2+, Co2+) in the presence of 10−2 M EDTA was studied. Under these conditions, the initial solution can be efficiently decontaminated from 60Co by its coprecipitation with NiS. The degree of coprecipitation of 60Co microamounts with NiS exceeds 95% at [Na2S]: [Ni2+] = (5–10): 1.
