摘要
简述了国内外贵金属分析常用的分离富集方法,包括火试金法、共沉淀法、萃取法、离子交换法、吸附法、液膜法等,并从多种分离富集方法联用的角度,介绍了2种分离贵金属元素的新方法:离子交换法与活性炭吸附的联用技术以及火试金法与Te沉淀的联用技术。最后对未来发展的趋势进行了展望。
Several methods were introduced briefly in present paper for the concentration and separation of precious metals at home and abroad, including fire assay, precipitation and co- precipitation, ion -ex- change, extraction, adsorption as well as some new separation methods such as supercritical fluid extrac- tion, liquid membrane separation. Furthermore, some associated techniques for the separation of precious metals were also described. Finally, the tendency for analysis of precious metals is prospected.
