Abstract

The kinetics of the Pu(VI) reduction with diformylhydrazine in a nitric acid medium 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 Pu, diformylhydrazine, and HNO3 is 1, 1.3, and–1.5, respectively. The activation energy of the reaction is 86.9 kJ mol–1.
