超临界流体萃取镧系和锕系元素研究进展北大核心CSCD

镧系和锕系元素的分离是核工业中研究的热点问题,常规的溶剂萃取法步骤复杂,在萃取过程中会产生大量的二次废液。超临界流体萃取(supercritical fluid extraction,SFE)技术是一种新型化工分离技术,由于其步骤简单、过程清洁,近年来该项技术应用于金属离子萃取方面的研究越来越多。本文综述了近十年来超临界流体(supercritical fluid,SCF)在镧系和锕系元素萃取方面的研究进展,发现目前的研究大部分集中在采用超临界萃取技术从各种复杂样品中萃取铀,通过对所用样品的对比与总结,分析了该技术在工业应用中的可能性。

Research Progress in Supercritical Fluid Extraction of Lanthanides and Actinides

The separation of lanthanides and actinides is the top priority in nuclear industry. The conventional solvent extraction method has complicated steps, and a large amount of secondary waste liquid will be generated during the extraction process. Supercritical fluid extraction technology is a new type of chemical separation technology. Due to it’s simple steps and clean process, more and more researches on the application of this technology to metal ion extraction have been carried out in the last few years. The research progress in the extraction of lanthanides and actinides has found that most of the current research has focused on supercritical extraction technology to extract uranium from various complex samples. Through the comparison and summary of the samples, it is analyzed the technology will be used in the industry.
