Separation of Cyclotron Produced In-111 (III) from Cadmium (II) and Copper (II) Ions Using Ion Exchange Technique in Different Media

Abstract

Hanafi HA and Abd El-Samad M

The commercial cation exchangers TSKgel BioAssist S, TSKgel CM-2SW and TSKgel CM-STAT have been used for the separation of 111In (III) from Cd (II) and Cu (II) ions. The separation was carried out using low cost cation exchangers based on the differences in the sorption affinity of In, Cu and Cd towards the ion exchanger from 0.01 mol L-1 HCl. The effects of various parameters such as shaking time, HCl concentration and acetate buffer concentration were examined. A comparative study between cation exchangers showed the best one for radiochemical separation yielded more than 98% within 50 min by using column study.
