The analysis of disproportionation of Pu(IV) and Pu(V) in nitric acid solutions at different concentrations showed that disproportionation of Pu(IV) follows an identical mechanism to that in perchloric acid. Because of complex formation, the equilibrium constant for the reaction 3Pu(IV) in equilibrium 2Pu(III) + Pu(VI) is an inverse ratio to nitric acid concentration at 5.3 deg C. The rate of disproportionation of Pu(V) in nitric acid solutions increases with hydrogen ion concentration. It is also shown that at the beginning the disproportionation of Pu(V) is determined by the reaction Pu(V) + Pu(V) in equilibrium ; Pu(IV) + (Pu(VI), but with the accumulation of Pu(III), the reaction Pu(V) + Pu(III) in equilibrium 2 Pu(IV) begins to prevail, leading to the autocatalytic acceleration of the process.
