用交联共聚的氯甲基苯乙烯阴离子交换树脂与含铀浸出液接触以吸附铀,然后,从树脂上淋洗铀以得到浓的铀溶液。选用硫酸作淋洗剂。较好的交联剂单体为二乙烯苯,其用量可为0.1—30%,采用1—10%更好,尤其在按总单体计算时可采用5—8%。催化剂如 The crosslinked copolymerized chloromethylstyrene anion exchange resin is contacted with the uranium-containing leachate to adsorb the uranium, and then, the uranium is leached from the resin to obtain a concentrated uranium solution. Sulfuric acid for showering agent. The preferred crosslinker monomer is divinylbenzene, which may be used in an amount of from 0.1 to 30%, more preferably from 1 to 10%, and especially from 5 to 8% by total monomer. Catalyst such as
