摘　　要：对核燃料后处理以及高放废液处理中所用的含磷萃取剂的辐照稳定性已经进行了广泛的研究。对正辛基苯基-N,N’-二异丁基胺甲酰甲基氧化膦(CMPO)、二(2-乙基己基)磷酸(DEHPA)以及混合三烷基氧化膦(TRPO)等的辐照稳定性的研究进行了综述。主要介绍了CMPO、DEHPA和TRPO的辐解产物;辐照对萃取和保留的影响以及辐照后溶剂的净化方法。Radiation stability of extractants containing phosphorus used in nuclear reprocessing has been widely investigated. Studies on the radiation stability of tributyl phosphate (TBP), octyl-phenyl-N,N'-diisobutylcalbamoy-Imethylphosphine oxide (CMPO), di(2-ethylhexyl) phosphorous acid(DEHPA), and trialkylphosphine oxide(TRPO), were reviewed. The radiolytic products of CMPO, DEHPA and TRPO, the effects of radiation on extraction and retention, and cleaning methods of irradiated solvents were introduced.
