【摘要】 在硝酸介质中,研究异丁醛（IBD）还原Pu（Ⅳ）反应的动力学性能和行为,通过考察Pu（Ⅳ）浓度、异丁醛和硝酸浓度等对Pu（Ⅳ）还原反应速率的影响,确定了反应的动力学速率方程。研究温度对速率的影响,求得反应活化能为51.7kJ·mol^-1。实验表明,异丁醛是Pu（Ⅳ）较好的还原剂。对还原反应的机理作了推测。更多还原

【Abstract】 The kinetics of Pu (IV ) reduction by isobutyraldehyde in nitric acid solution has been studied. The rate equation of reaction has been determined after effect factor test of Pu (IV ) concentration, isobutyraldehyde concentration and nitric acid concentration. The reaction rate affected by temperature has been reseached and the activation energy (51. 7 kJ .l mol-1) has been found. The results indicate that isobutyraldehyde is a fairly reductant to Pu (IV ). The reaction mechanism has been predicted.更多还原
