摘　　要：高放废液的处理处置是影响核能可持续发展的重要因素。从高放废液中分离出90 Sr不仅能实现高放废液的安全处置,也具有较高的经济意义。本文在早期研究的基础上,结合近些年的研究情况,从沉淀法、离子交换法、溶剂萃取法、色层分离法和膜分离法5个方面介绍了从高放废液中分离90 Sr的方法,并进行了讨论。最后指出目前研究工作中存在的不足,并对其前景进行了展望。The safety management of high level liquid waste（HLLW） is one of the most important factors in the sustainable development of nuclear energy.Removal of 90Sr from HLLW not only reduces the radiation fields in subsequent fuel cycle reprocessing streams,but also has certain economic value.The methods used in the partitioning of 90Sr from HLLW include the precipitation method,the ion exchange,the solvent extraction,the chromatography and the membrane separation.It has been proved that the solvent extraction is the most effective way used in industrial scale and the chromatography is also promising.Although the present work is attractive,there are still problems to be solved.Finally,the prospects of the development of these fields were also discussed.
