摘要
超临界流体络合萃取是1种可用于萃取金属离子的新型分离技术,它应用于乏燃料后处理和核废物处理中的最大优点是能大幅减少二次废物的产生。文章主要介绍超临界流体的特点、超临界流体络合萃取的基本原理及其影响因素,并对超临界流体络合萃取镧系和锕系元素的研究进展及其在乏燃料后处理工艺研究中的应用进行综述。
Supercritical fluid chelating extraction （SFCE） is a new type of separation technology for extracting metallic elements. When SFCE is used in both the spent fuel reprocessing and the treatment of nuclear wastes, the generation of second wastes can be minimized. Both the properties of supercritical fluid and the theory of SFCE were introduced, and factors affecting SFCE were discussed in the paper. The research progress on SFCE of lanthanides and actinides and applications in the process study of spent fuel reprocessing were reviewed too.
