摘　　要：介绍了国内外几种常用的去除中药中重金属的方法,重点介绍了超临界CO2配合萃取去除重金属方法的配合萃取原理、配合萃取过程的影响因素、配合剂的选择、中药中重金属的存在形态与配合萃取的关系、重金属的形态分析方法等,指出目前超临界CO2配合萃取重金属存在的问题,并对今后的研究趋势进行了展望。Several common methods that used to get rid of heavy metals from the traditional Chinese medicine were summarized. And removing heavy metals by supercritical chelating extraction was recommended especially. The theory of supercritical chelating extraction, influencing factors during the progress of chelating extraction, choice of chelating agent, relation between existent shape and chelating extraction, shape analysis of heavy metals in traditional Chinese medicine were introduced. The problems of supercritical CO2 chelating extraction of heavy metals at present and the research trend in the future were discussed.
