摘要
在T.J.Tayler和H.C.Urey用离子交换法分离锂同位素之后,相继有不少用离子交换剂分离锂同位素的研究工作发表。M.Okamoto在离子交换膜电迁移浓缩锂同位素的研究中作了不少工作。H.Kakihana发表了阳、阴离子交换膜交替组合的多单元电渗装置分离锂同位素的专利报告,引起了人们的兴趣。
The capability of cation exchange memberanes, sulphomembranes of polyvinylidene fluoride, in separating lithium isotopes is determined exerimentally by single depletion and multi-stage enrichment. The separation factors,α6/7, are 0.9986-0.9967 and 1.0012-1.0018 respectively.α6/7 is effected by the degree of cross-linking of the membranes. The sulphomembrane of polyvinylidene fluoride with 15% cross-linking gives the best separation, with α6/7=0.9967.
