Abstract
A new approach to the destructive processing of the cation-exchange resin KU-2×8-M (M = Cs, Ni, Cu, Fe, Nd, U) based on its gas-phase treatment in a nitrating atmosphere with subsequent chemical treatment of the conversion products is considered. It is shown that exposure of KU-2×8-M samples (M = Cs, Ni, Cu, Fe, Nd, U) in an HNO3(vapour)-air atmosphere at temperatures of 403-443 K for 8 and 24 h followed by dissolution conversion products in 0.5 mol∙L-1 NaOH and ozonation of the resulting solutions allows e cient utilization of the KU-2×8-M resin (M = Cs, Ni, Cu, Fe, Nd, U).
