| 摘 要： | 为了得到低铀细菌浸出液培养浸矿菌种，以细菌浸出液为吸附原液，采用了静态和动态实验方法，研究717#强碱阴离子交换树脂的饱和吸附性能。因细菌浸出液的Fe^3 0与铀共存于树脂上，实验以抗坏血酸去除铁的影响。对铀的分离研究表明：该树脂对铀吸附性能好，铀回收率高，每克干树脂的吸附铀容量可达62．2mg，单位体积的湿树脂的吸附容量为145．7mg。

| Abstract: | Directed at obtaining bacteria leaching solution of low uranium, the study is focused on the uranium recovery from bacteria leaching with anion-exchange resin 717#, applied into bacteria leaching solution, by dynamic method and static method. The study shows that vitamin C is used to remove Fe3+ in the bacteria leaching solution remaining in the resin, coupled with uranium. The study shows that the resin offers a better adsorbing capacity for uranium and a higher uranium recovery. Dry resin shows an adsorbing capacity of 62.2 mg uranium per gram and wet resin an adsorbing capacity of 145.7 mg uranium per unit volume. |
