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.

Tokem-308 树脂气体转化产物的定位

摘要研究了 Tokem-308 阳离子石（KU-2x8 的类似物）在 HNO3（蒸气）-空气气氛中气相转化的产物溶解过程中形成的化合物，这些产物是由 12 M HNO3 在 H2O 以及 0.045 和 0.5 M NaOH 溶液中气化得到的。还研究了对这些产品的碱性溶液进行臭氧处理以利用后者的问题。在 HNO3（蒸气）-空气气氛中进行气相处理，在 NaOH 溶液中溶解，然后进行臭氧处理，这一系列过程使得碱性溶液几乎不含任何有毒的芳香族杂质，因此适合安全处理。
