Kinetics and mechanism of stripping of Pu(IV) by N,N-dimethylhydroxylamine using a Lewis cell
- 1. China Institute of Atomic Energy, Beijing (China). Department of Radiochemistry
Description
The kinetics of back-extraction of Pu(IV) from 30% Tri-Butyl-Phosphate/Odourless Kerosene (TBP/OK) into a nitric acid solution containing N,N-dimethylhydroxylamine (DMHAN) have been investigated using a Lewis cell. The different parameters affecting the back-extraction rate of Pu(IV) such as plutonium, nitric acid, DMHAN concentration in addition to temperature, stirring speed were separately studied and a rate equation was deduced. The activation energy of this process is 28.4 kJ/mol. (author)
