ABSTRACT:
Radioactive organic wastes such as anion-exchange resins, chelate resins and organic filter sludges are readily oxidized by reacting hydrozen peroxide in an aqueous medium in the presence of iron-ions or both iron-ions and cation-exchange resin to be decomposed to carbon dioxide and water. Contact between the wastes to be decomposed and hydrogen peroxide is preferably conducted by continuously feeding hydrogen peroxide or both hydrogen peroxide and the wastes to be decomposed to the reaction zone.
