Abstract
More than 99% of radioactive cobalt can be removed from water by precipitation as cobalt/III/ hydroxide. The process is continuous and uses either sodium hypochlorite or oxygen and calcium sulfite to oxidize the cobalt. Carbonate and phosphate interfere with cobalt removal, but the process has potential for other applications such as thallium removal and sewage treatment.
