摘要

综述了不同电渗析体系对盐湖中锂的分离效果，包括单选择性电渗析、离子液膜、双极膜，其中离子液膜具有对Li+的高度识别、电解下的长期稳定性和低能耗等特点，发展前景较为广阔；分析了不同电渗析体系在盐湖提锂中的优缺点及未来发展趋势，以及推动应用电渗析体系进行盐湖提锂的工业化研究。

Abstract

This paper summarized the separation effects of different electrodialysis systems on lithium in Salt Lake, including single selective electrodialysis, ionic liquid membrane and bipolar membrane, among which ionic liquid membrane with a broad development prospect possesses the characteristics of high recognition of Li+, long?term stability under electrolysis and low energy consumption. Furthermore, the advantages, disadvantages and tendency of prospective development of different electrodialysis systems in lithium extraction from Salt Lake were analyzed, and the industrialization research on the application of electrodialysis systems for lithium extraction from Salt Lake was analyzed.
