摘要
本文概述了钋-210的主要特性及用途,简要介绍了其制备的意义及难度,重点针对可实现钋-210批量化制备的核反应堆中子辐照技术路线,从高温蒸馏法、氢化提取法、碱提取法、稀土提取法、自电镀法、溶剂萃取法等方面综述了辐照后铅铋靶材中钋-210的分离提取技术研究现状,最后对有望实现批量化制备的钋-210分离提取技术进行了展望。
The paper summarizes the main characteristics and uses of polonium-210,briefly introduces its significance and difficulty in preparation,focuses on the neutron irradiation technology route of the nuclear reactor that can realize the batch preparation of po-lonium-210,and the research status of polonium-210 separation and extraction technology from irradiated Lead-Bismuth target was reviewed from the aspects of high-temperature distillation,hydrogenation extraction,alkali extraction,rare earth extraction,self-elec-troplating and solvent extraction.Finally,the Polonium-210 separation and extraction technology,which is expected to be prepared in batches,is prospected.
