This study reports the extraction of U(VI) using poly(vinyl chloride)-based polymer inclusion membrane (PIM), possessing the extractant alamine336 and the plasticizer Polyoxyethylene alkyl ether (POE). The effects of transport parameters such as alamine336 and POE concentration in the PIM composition, uranium and sulfuric acid concentration in the feed phase, and the receiving phase type and concentration were discussed. Under the optimum conditions, 91.02 ± 2% of uranium was transported through the PIM. The prepared PIM showed excellent selectivity for U(VI) from the sulfuric acid leach solution. The stability of the PIM was found to be acceptable for 5 days.

使用含alamine336的聚合物包合物膜从硫酸介质中选择性分离铀

这项研究报告使用具有萃取剂alamine336和增塑剂聚氧乙烯烷基醚（POE）的聚（氯乙烯）基聚合物包裹膜（PIM）萃取U（VI）。讨论了传输参数如PIM组合物中的alamine336和POE浓度，进料相中的铀和硫酸浓度以及接收相的类型和浓度等影响。在最佳条件下，通过PIM输送了91.02±2％的铀。制备的PIM对硫酸浸出溶液中的U（VI）具有极好的选择性。发现PIM的稳定性在5天内是可接受的。
