摘　　要：简述了从溶液中萃取镁的研究发展历程,分别介绍了胺类萃取剂、中性萃取剂、螯合萃取剂以及酸性萃取剂萃取镁的过程和萃取基本原理,溶剂萃取镁的技术主要用在物质的分离提纯中除去镁杂质、废水净化处理、资源化回收镁等。总结了溶剂萃取镁的研究应用现状,以及溶剂萃取镁在工业化应用中存在的不足之处。并对萃取镁的研究新方向作了简要介绍,有待进一步深入研究。This paper describ＇es the course of research and development of the extraction magnesium from the solution. It respectively introduces the extraction magnesium process and basic principle of amine ex- tractant, neutral extraction agents, chelating agents and acidic extraction agent. Solvent extraction magne- sium technique is mainly used for removing the impurity of magnesium in separating and purifying substances, purifying wastewater and recovering the resource of magnesium. It briefly summarizes the research status of magnesium solvent extraction. It points out the deficiencies in solvent extraction of magneslum present in industrial applications. Some new directions of magnesium extraction are briefly introduced, needing for further research.
