Abstract
The kinetics of the Np(VI) reduction with diformylhydrazine in a nitric acid solution was studied by spectrophotometry. The reaction rate increases with an increase in the reductant concentration and temperature and decreases with an increase in the HNO3 concentration. The reaction order with respect to Np, diformylhydrazine, and HNO3 is 1, 1.3, and–1.55, respectively. The activation energy of the reaction is 85 ± 10 kJ mol–1.
