摘　　要：随着我国核电工业的快速发展,核燃料铀的需求越来越多。文章采用了201×7、D354FD、UA2100树脂进行了从某铀矿浸出液中回收铀的实验研究,即对铀浓度为43 mg/L的某铀矿浸出液进行静态和动态吸附,结果表明,201×7、D354FD和UA2100树脂的静态吸附容量分别为17.61 mg/m L、18.97 mg/m L、32.7 mg/m L,动态吸附容量分别为20.05 mg/m L、25.31 mg/m L、41.21 mg/m L。UA2100树脂对浸出液中铀的吸附性能和淋洗效果均明显优于D354FD和201×7树脂。With the rapid development of China＇s nuclear power industry, the demand for uranium nuclear materials more and more. The experiment using 201×7, D354 FD and UA2100 resins recovered uranium from a certain uranium ore leachate. The results showed that static adsorption and dynamic adsorption about the uranium concentration of 43 mg/L of the uranium ore leachate by 201×7, D354 FD and UA2100 resins, static adsorption capacity were 17.61 mg/m L, 18.97 mg/m L, 32.7 mg/m L. The dynamicad sorption capacity was 20.05 mg/m L, 25.31 mg/m L, 41.21 mg/m L. UA2100 resin of adsorption and leaching effects were significantly better than D354 FD and 201×7 resins.
