摘要：
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)x 10(-3) M-1.2 min(-1) at 294 +/- 1K. The activation energy of the reaction was 76 +/- 5 kJ/mol.
