Abstract
Hydrazine is added to low-level radioactive waste, and the waste is contacted with an iron hydroxide-cation exchange resin so that its radioactive concentration may be lowered. The resin is a strongly acid cation exchange resin treated with ferric chloride and aqueous ammonia and containing a product of hydrolysis of ferric ions.
