- Аннотация: The paper considers a new approach to the destruction of the Tokem-308 cation-exchange resin (analog of KU-2-8). The method is based on the gas-phase treatment of the resin in a nitrating atmosphere, followed by chemical treatment of the conversion products. It has been shown that the treatment of Tokem-308 in the NOx–H2O (vapor)–air atmosphere at 403–443 K for 4–24 h with the subsequent dissolution of the conversion products in 0.5 mol/L NaOH and ozonation of the obtained solutions allows an effective destruction of Tokem-308 to be carried out.
