摘　　要：稀土萃取分离是实现稀土资源高效利用最重要步骤,因此,萃取分离技术的优缺点及萃取剂的性能好坏将是决定萃取过程中分离能力和分离效率的关键。本文简要概述了近年来稀土萃取分离提纯技术的发展概况及萃取剂的研究进展,并结合稀土萃取剂构效关系研究情况,展望了新型稀土萃取剂的发展方向。Rare earth extraction and separation is the most important step to realize the efficient utilization of rare earth resources. Therefore,the characteristics of the extraction separation technology and the performance of the extractant are the keys to determine the separation capacity and separation efficiency in the extraction process. This paper briefly summarizes the development of rare earth extraction and separation technology in recent years and the research progress of extractants. Combined with the research on the structure-activity relationship of rare earth extractants,the research direction of new rare earth extractants is prospected.
