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

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 HNO 3 concentration. The reaction order with respe...

Zusammenfassung: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 HNO 3 concentration. The reaction order with respect to Np, diformylhydrazine, and HNO 3 is 1, 1.3, and–1.55, respectively. The activation energy of the reaction is 85 ± 10 kJ mol –1 .
