Direct Preparation of ³⁵S-Labeled Copper Sulfate

Abstract

A novel method was developed for preparing ³⁵S-labeled Cu³⁵SO₄•5H₂O directly from neutron irradiated KCl. One gram of neutron irradiated KCl was dissolved in water and passed through a cation exchange resin column in Cu²⁺-form for the purpose of converting KCl to CuCl₂. In the presence of carrier sulfate, the precipitates of ³⁵S-labeled sulfate were separated from the effluent by the addition of ethanol. Factors affecting the recovery and quality of the final products were studied and a standard procedure was devised at optimum conditions.
