Reduction of Neptunium(VI) by Butyraldehyde Isomers in Nitric Acid Solution

Abstract

The kinetics of the reaction between Np(VI) and butyraldehyde isomers in nitric acid solution was studied to find flow-sheet conditions of the Np separation process from U and Pu. Iso-butyraldehyde was found to have a higher reduction rate than n-butyraldehyde. The former reduction rate at T = 283 to 323 K is described by the following equation:.The latter reduction rate is described by the following equation:.
