Resumo
The kinetics of the Pu(VI) reduction with carbohydrazide in nitric acid solutions was studied by spectrophotometry. The reaction rate increases with increasing carbohydrazide concentration and temperature and decreases with increasing HNO3 concentration. The reaction order with respect to Pu, carbohydrazide, and HNO3 is 1, 2.3, and–3, respectively. The activation energy of the reaction is 111 kJ mol–1. The final reduced Pu form is Pu(III), with Pu(V) being an intermediate.
