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.
