520 3 |a The reduction kinetics of Np(VI) by n-butyraldehyde in 30% TBP solution diluted with n-dodecane were analyzed by spectrophotometry. Based on the results of both n-butyraldehyde and nitric acid concentration dependences on the Np(VI) reduction reaction, the rate equation was obtained as -d[Np(VI)]/dt=k[n-C3H7CHO]0.8[HNO3]-2.0[Np(VI)]t where k=(1.0±0.2)× 10-3M1.2 min-1 at 294±1K. The activation energy of the reaction was 76±5kJ/mol.
