离子印迹聚合物在废水离子分离方面具有巨大的潜力。然而，膜分离离子的困难是众所周知的，这严重制约了膜技术在工业废水金属资源回收中的应用。本文提出了一种合理的分子水平设计方法来修饰PVDF膜上的离子印迹聚合物层。在离子印迹膜(IIM)中，沿着膜孔制备了特异的主-客体结合位点。单体剂量越大，对Cd2+的排斥程度越高，IIM中的结合位点越多。IIM与Cd2+的结合是非离子印迹膜(NIM)的1.84倍。在混合离子溶液中，IIM的渗透选择性因子(γ)大于5.39。化学特性和密度泛函理论(DFT)计算显示,官能团的Cd2+识别网站CS和CS Cd2+大规模运输IIM表明印记效应提供了一种约束力,延迟Cd2+渗透通过IIM,以便与其他离子选择性分离Cd2+。印迹效应可能会启发一种新的分子水平的膜设计方法，以提高离子的选择性。

Ionic imprinted polymers have great potential in wastewater ion separation. However, the difficulty of membrane separation of ions is well known, which seriously restricts the application of membrane technology in the recovery of metal resources from industrial wastewater. This article proposes a rational molecular level design method to modify the ion imprinted polymer layer on PVDF membrane. In the ion imprinted membrane (IIM), specific host guest binding sites were prepared along the membrane pores. The higher the monomer dose, the higher the degree of rejection of Cd2+, and the more binding sites in IIM. The binding of IIM to Cd2+is 1.84 times that of non-ionic imprinted membrane (NIM). In mixed ionic solutions, the permeability selectivity factor (γ) of IIM is greater than 5.39. Chemical properties and density functional theory (DFT) calculations show that the recognition of functional groups by Cd2+sites and the large-scale transport of CS Cd2+by IIM indicate that imprinting effect provides a constraint to delay the penetration of Cd2+through IIM, in order to selectively separate Cd2+from other ions. The imprinting effect may inspire a new molecular level membrane design method to improve ion selectivity.
\nThe research dataset on the delayed permeation mechanism of Cd2+selective separation enhanced by ion imprinted membrane was obtained experimentally in decimal (. xls) format, with a total of 21104 data sets.
