本文提出了以季铵盐为萃取剂,在加入过氧化氢的条件下,从(NH_4)_2CO_3-(NH_4)_2SO_4溶液解吸某铀水冶厂含铀、钼树脂所得的料液中分离铀、钼的新方法。结果表明,当料液中含铀4—5g/L、钼～2g/L时,季铵盐浓度为0.15mol/L,加入过氧化氢0.8％(v/v),相比(有/水)为1/4,经一段萃取,钼的萃取率可达97.9％,负载有机相中含铀小于0.1g/L。
In this paper, we propose to use quaternary ammonium salt as extractant to extract uranium from the feed solution of (NH_4) _2CO_3- (NH_4) _2SO_4 solution containing uranium and molybdenum resin in a uranium watermelting plant under the condition of adding hydrogen peroxide, New method of molybdenum. The results showed that the quaternary ammonium salt concentration was 0.15mol / L and the content of hydrogen peroxide was 0.8% (v / v) when uranium was 4-5g / L and molybdenum was 2g / L, ) For 1/4, after a period of extraction, molybdenum extraction rate of up to 97.9%, containing the organic phase containing uranium less than 0.1g / L.
