Resumo
The kinetics of the Np(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 Np, carbohydrazide, and HNO3 is 1, 1.15, and–1.35, respectively. The activation energy of the reaction is 85 kJ mol–1.
