Electrolytic reduction mechanism of Np(V) and the effect of coexisting nitric acid

Kitatsuji, Yoshihiro ; Kimura, Takaumi ; Kihara, Sorin*

The behaviors of reduction of Np(V) by controlled potential electrolysis were studied, and a unique time course of electrolysis current was observed. It was conclude that Np(V) was reduced by two reduction processes that are the chemical reaction with Np(III) and the electrocatalytic reduction by adsorbed hydrogen atom on platinum electrode surface. The time course of current for controlled potential electrolysis of Np(V) under various condition of the solution was investigated, and the effects of the concentration of H $^{+}$ and NO $_{3}$ $^{-}$ on electrolysis behaviour were shown.
