离子液体的微波合成及其对Cu^(2+)萃取率的研究

Synthesis Using Microwave and Study on Extractive ratio to Cu^(2+) of N,N'-dialklimidazolium-based Ionic Liquids

离子液体作为一种环境友好的绿色溶剂正越来越多的受到关注。本文试验了以疏水性离子液体二烷基咪唑类六氟磷酸盐作为溶剂,加入不同的萃取剂,液液萃取水中的Cu^(2+),并收到了较好的效果;离子液体中的Cu^(2+)经电镀回收,同时离子液体通过回收可再次使用,真正实现离子液体在萃取分离过程中的绿色化。

Ionic Liquids,as environmentally benign and green solvent,are attracting more and more attention.In this paper,Cu^（2＋）in water were extracted using hydrophobic N,N＇-dialklimidazolium-based ionic liquid as solvent,which different extracting agents were joined in the ionic liquid.Cu^（2＋）were reclaimed by galvanization in the io-nic liquid.As the same time ionic liquids were recurrent by reclaiming,which realized ionic liquids are grassy in the extraction and separation.
