摘　　要：电解浓缩法是环境氚水样进行浓缩的主流方法,能否获得较高的回收率是评价电解浓缩系统性能的主要标志。回收率可通过氚分馏系数和电解浓缩倍数计算获得。电解系统的氚分馏系数定量描述电解水反应氚动力学分馏的参数,代表了电解水系统的性能。在电解水时,加入标准氚水,电解后进行测量,可以得到当次电解水的回收率,由此计算出电解水的氚分馏系数,根据氚分馏系数可用于下批次的回收率计算。Electrolytic enrichment - liquid scintillation counting is the main method to measure the tritium activity from environment samples. The tritium recovery is the main evaluation index of electrolytic enrichment system. The recovery can be calculate by a function of the tritium fractionation factors and enrichment times. The tritium fractionation factor of electrolytic enrichment system is a parameter which describe the tritium dynamic fractionation in the reaction of Water Electrolysis. This parameter represents the Property of the Water Electrolysis system. Before the water electrolyze, added with tritium standard water, the recovery of the present time is obtained by measurement after electrolyze. Then the tritium fractionation factor is obtained and it can be used to calculate the tritium recovery of next time.
