Mechanisms of Plutonium(III–VI) Redox Reactions in Solutions with pH above 1 Radiochemistry Pub Date : 2023-08-07 V. P. Shilov
Abstract The published data were analyzed on the stability of 239Pu(VI, V, IV) in aerated solutions with pH > 1 up to pH 14 during long-term storage. Under the action of the products of α-radiolysis of water, mainly H2O2, plutonium (80–85%) converts into Pu(IV) hydroxide. Н2О2 partially oxidizes Pu(IV), which leads to a stationary concentration of Pu(V), while in a 0.1 M NO3– solution, to a stationary
