Abstract: This article described the traditional methods of separation and enrichment for indium, including precipitation, ion exchange process, solvent extraction, etc, and the advantages and disadvantages of each method and the development trend in future research. The article focused on the analysis of liquid membrane method, levextrel resin method, chelating resin method, solvent microencapsule method, flotation, nanotechnology and other new technologies. The indium can be effectively separated under proper conditions. More study is needed to improve stability of separation materials, separation mechanism and mass transfer mathematical models, in order to develop techniques for waste water containing indium(Ⅲ) with low energy consumption and low cost .

Key words: indium, separation, enrichment, solvent extraction, nanomaterials

摘要: 我国铟资源在世界上处于绝对的优势地位, 但国内生产工艺水平低, 导致大量原生铟在生产加工过程中流失, 严重阻碍我国高新技术产业的发展。而铟具有很好的再生性, 国内外不少学者对铟的富集回用做出研究。文章回顾了传统分离富集法, 主要包括沉淀法、离子交换法和溶剂萃取法等, 简述了各个方法的优缺点及未来的发展趋势, 并着重分析了目前分离富集铟的新型方法:液膜法、萃淋树脂法、螯合树脂法、溶剂微胶囊法、浮选法及纳米技术等。指出在合适的条件下, 运用这些技术可对铟进行有效地分离回收, 并对分离富集铟的技术发展作出展望:加强这些技术所使用分离材料的稳定性、分离机理以及传质模型的研究, 以期发展出具有低能耗、低成本的优势技术。
