金的分离富集

综述了金的分离和富集方法，主要包括各种吸附和萃取方法。采用活性炭和泡沫塑料(简称泡塑)吸附分离金是传统的分离富集法，有负载活性炭和有负载泡塑可以提高富集金的能力。近些年，离子交换树脂和离子交换纤维素在分离富集金的应用中，占有相当大的比例。萃取法除了使用传统的MIBK作为萃取剂，又见报道硫醚、亚砜、醇类等作为萃取剂的各种萃取体系。中引用参考献107篇。

Separation and enrichment of gold

The methods of gold separation and enrichment including a variety of adsorption and extraction methods are overviewed.To adsorb and separate gold with activated carbon or foam plastics is traditional method.By using load activated carbon or load foam plastics,the enrichment capacity of gold can be enhanced.In the recent years,the application of ion exchange resin and ion exchange cellulose to gold enrichment occupied considerable percent.According to report,sulfur ether,sulfoxide and alcohol have been used as extractants besides the traditional extractant MIBK.107 literatures are cited in this paper.
