- Аннотация: The analysis of published data on disproportionation reactions of actinides in aqueous solutions of acids, carbonates, and alkalis, in solutions of unsaturated heteropoly compounds, chelators, in organic media containing extractants was carried out. It is shown that the dependence on [H+] and the order by H+ are related to the difference in the standard potentials of the emerging and reacting ion pairs. The course of reactions is complicated by the formation of cation–cation complexes An(V)–An(VI) and others. The conditions are determined under which actinides in one or another oxidation state remain resistant to disproportionation. Among the unresolved issues, it should be noted the desirability of studying these reactions in solutions of fluorides, H3PO4, unsaturated heteropolycompounds, crown ethers, porphyrins, in the presence of extractants.
