摘　　要：合成了一种伯胺树脂,对钍具有很好的选择性,当钍浓度为125mg/L时,吸附钍的分配比达到2.48×103。与铁和铈的分离系数分别为1.29×104和9.7×104,吸附钍的最佳[SO42-]=1.0mol/L,[H+]=0.1mol/L,接触时间5min。对钍的去除率大于99%,处理液中钍浓度<0.001mg/L。One type of primary amine resin was syethesized, which had excellent selectivity to Th, and distribution ratio of adsorbing Th could be up to 2.48×10^3 when concentration of Th was 125mg/L. The speration coefficient of this resin with Fe and Ce were 1.29×10^4 and 9.7×10^4 ,respectively. The best condition for Th adsorption was： [SO4^2-] = 1.0mol/L, [H^＋] = 0.1mol/L, contacting time was 5 min. The removal rate of Th was over 99%. and concentration of Th was less than 0. 001mg/L.
