选择性吸附贵金属离子的螯合树脂的研究进展

Progress of absorption of precious metal ions of chelating resins

树脂矿浆法(RIP)从溶液中提取与分离贵金属是目前的研究热点,其关键是制备高吸附容量和高吸附选择性的螯合树脂。讨论了选择性吸附贵金属离子的螯合树脂的分类方法、树脂结构与性能的关系、树脂与贵金属离子的配位机理,按配位原子分类综述了近10年来国内外螯合树脂的合成和吸附的研究进展,并展望了螯合树脂研究的发展方向。

Resin-in-pulp（RIP） method is one of the hot research topics in extraction and separation of precious metals from solutions,and the preparation of chelating resins with high adsorption capacity and high selectivity is the key to this technique.The classification of chelating resins,the relationship between structure and property of chelating resin,and the chelating mechanism of chelating resin and precious metal ions were discussed,the synthesis and adsorption property of chelating resins in recent 10 years was reviewed,and the trend of chelating resins was forecasted.
