| Abstract: | :The two naturally occurring isotopes of lithium (6Li and 7Li) occupy important roles in the atomic energy industry.Among the methods for the separation of lithium isotopes,solvent extraction is a method which not only have a higher isotope separation factor,but also is the most promising method expected to achieve industrial production with nontoxicity and higher efficient.Hence,in this paper,we simply illustrate the method of solvent extraction separation of lithium isotopes,and summarizes the alcohols and ketones,the alkylphosphines and phosphonates,the crown ethers and the other solvent extraction systems in the separation of lithium isotope.We also prospect its potential applications in separation of lithium isotopes and to develop a high-value utilization of lithium resources in salt lakes of Qinghai and Tibet. |
