Kinetics of Pu(VI) Reduction with Diformylhydrazine in Nitric Acid

Аннотация

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.
