总结用分光光度法分析了在用正十二烷稀释的30%TBP溶液中正丁醛还原Np（VI）的动力学。在294±1 K下，正丁醛和硝酸浓度对Np（VI）还原反应的影响关系为-d[Np（VI）]/dt=k[n-C3 H7 CHO]0.8[HNO 3]-2.0[Np（VI）]t，其中k=（1.0±0.2）× 10- 3M1.2min-1。反应的活化能为76±5 kJ/mol。
Summary 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)× 10–3 M1.2 min–1 at 294±1 K. The activation energy of the reaction was 76±5 kJ/mol.
