Abstract
Electrolysis with glassy-carbon electrodes was employed as a preliminary separation step prior to thermal neutron irradiation. Low parts per billion of gold in cadmium metal was electrodeposited on a glassy-carbon cathode from hydrochloric acid-nitric acid solution in greater than 90% yields, leaving about 99.999% of cadmium in the electrolyte. The golddeposited electrodes were then irradiated in a nuclear reactor. About 6 parts per billion of gold was found in a sample of commercial high-purity cadmium metal (purity 99.999%) .
