锂同位素6Li和7Li是核聚变所需的重要材料，故锂同位素分离是核能发展必需解决的难题。本文通过介绍大环聚醚溶剂萃取分离锂同位素及大环聚醚聚合物离子交换色层法分离锂同位素的概况，综述了国内外大环聚醚及其固载化聚合物在锂同位素分离方面的研究现状及发展趋势，其中淋洗色谱法和膜色谱法是锂同位素分离的未来发展方向之一。

Lithium isotopes 6Li and 7Li are the required materials in the nuclear fusion reactions. The development of lithium isotope separation is of great importance during nuclear energy development. This paper introduced the overview of using the macrocyclic polyether and macrocyclic polyether polymer as chemical exchanger to separate lithium isotopes through solvent extraction and ion exchange chromatography. It also reviewed the research status and development direction of macrocyclic polyether and its immobilized polymer in lithium isotope separation and analyzed its relative mechanism. Macrocyclic polyether polymer as chemical exchanger, elution chromatography and membrane chromatography would be the development direction of lithium isotope separation in the future.
