RADIOCHEMICAL SEPARADION OF CARRIER-FREE SILVER, CADMIUM, AND RHODIUM FROM EACH OTHER BY SOLVENT EXTRACTION

Technical Report ·
OSTI ID:4702502
In some carrier-free radiochemical procedures for the analvsis of fission products, the rhodium, silver, and cadmium radionuclides are separated by ion exchange. They are adsorbed preferentially on an anion column from weak hydrochloric acid solution. Most of the Rh/sup 105/ is eluted first, but since there is tailing, some rhodium will be found with the silver and cadmium fractions. In order to reduce this contamination, two reagents, triiso-octyl thiophosphate and triiso-octylamine, were tested as liquid extractants for the three elements. Partition coefficients were obtained and from these a method was developed for the individual separation of silver and of cadmium from rhodium. (auth)
