This study aims at comprehensively investigating the possibility of fabricating cross-linked polymer inclusion membranes (PIMs) using the most common base polymers (i.e., poly(vinyl chloride), cellulose triacetate and poly(vinylidene fluoride-co-hexafluoropropylene)), cross-linking polymers or monomers (i.e., poly(ethylene glycol) dimethylacrylate, poly(ethylene glycol) divinylether and N-ethylmaleimide) and photo-initiators (i.e., 2,2-dimethoxy-2-phenyl acetophenone, triarylsulfonium hexafluorophosphate and triphenylphosphine oxide). The suitability of the photo-initiators for the different cross-linking polymers/monomers in poly(vinyl chloride)-based membranes (without extractants) was assessed for the first time, which was followed by optimizing the cross-linking conditions (i.e., membrane composition and duration of UV-irradiation) for all three base polymers studied. The optimum concentrations of photo-initiator and UV-treatment times were different for the different base polymers used, thus highlighting the importance of this study. Aliquat 336 and di-(2-ethylhexyl)phosphoric acid, as the most frequently used PIM extractants, were added to the compositions of the homogeneous cross-linked membranes produced under optimal conditions and the extraction performance of the newly developed cross-linked PIMs was compared with that of their non-cross-linked counterparts in the extraction of SCN⁻ and Zn²⁺, respectively. The results showed that all but one of the 13 homogeneous cross-linked PIMs obtained in this study could extract up to 45% more of the corresponding target species than their non-cross-linked counterparts and the remaining one performed similarly to the relevant non-cross-linked PIM. The initial fluxes for the cross-linked PIMs were up to 10 times higher than those of the relevant non-cross-linked membranes and in two cases the fluxes were similar in value. These results demonstrate the potential of cross-linking for enhancing the extraction performance of PIMs.

本研究旨在利用最常见的基础聚合物（即，聚（氯乙烯），三乙酸纤维素和聚全面调查制造交联的聚合物夹杂物膜（PIMS）的可能性（偏二氟共-六氟丙烯）），交联聚合物或单体（即，聚（乙二醇）二甲基丙烯酸酯，聚（乙二醇）二乙烯基醚和N-乙基马来酰亚胺）和光引发剂（即2,2-二甲氧基-2-苯基苯乙酮，六氟磷酸三芳基ulf和三苯基膦氧化物）。首次评估了光引发剂在聚氯乙烯基膜（不含萃取剂）中对不同交联聚合物/单体的适用性，然后优化了交联条件（即膜所研究的所有三种基础聚合物的紫外辐射的组成和持续时间）。对于使用的不同基础聚合物，光引发剂和紫外线处理时间的最佳浓度是不同的，因此凸显了这项研究的重要性。Aliquat 336和二（2-乙基己基）磷酸^-和Zn ²⁺。结果表明，在这项研究中获得的13种均质交联PIM中，除一种外，其余所有均能比其非交联对应物提取多达45％的相应目标物种，其余一种与相关的非交联PIM类似。交联的PIM。交联PIM的初始通量比相关非交联膜的初始通量高10倍，在两种情况下，通量的值相似。这些结果证明了交联增强PIM提取性能的潜力。
