| Abstract | Pu(IV) is reduced to Pu(III) in nitric acid solutions with formic acid in the presence of urea and 1% Pt/SiO2 catalyst. The kinetics of reduction were studied in 0.3-2.3 M HNO3 containing 0.2-1 M HCOOH, 0.1-0.5 M (NH2)2CO, and 0.01-0.1 g ml-1 of 1% Pt/SiO2 at 30-60°C. At HNO3 concentration higher than 2 M, the Pu(IV) reduction is reversible because of catalytic decomposition of urea. The reduction mechanism is discussed. |
