Abstract—The chemical compounds formed during the dissolution of the products of gas-phase conversion of the Tokem-308 cationite (analog of KU-2x8) in an HNO3(vapor)–air atmosphere, obtained by vaporization of 12 M HNO3, in H2O and 0.045 and 0.5 M NaOH solutions were studied. Ozonation of the alkaline solutions of the products was studied for utilization of the latter. The sequence of procedures including gas-phase treatment in the HNO3(vapor)–air atmosphere and dissolution in NaOH followed by ozonation makes it possible to obtain alkaline solutions almost without any toxic aromatic impurities, due to which the solutions are suitable for safe disposal.
