Conclusions
-
1.
The pulse radiolysis method was used to study the reaction rate of Np(VI) with O− in aqueous alkaline solutions. The rate constants of the reaction in LiOH and NaOH solutions were determined.
-
2.
The rate constant for the reduction of Np(VII) by Np(V) is independent of the LiOH concentration. The reduction proceeds more slowly in NaOH solutions.
