The transport behaviour of Cr(VI) from the aqueous phase through a polymer inclusion membrane (PO-PIM) containing 1-octanol (OCT) as carrier and polyvinyl chloride (PVC) as support at a low voltage drive (0–30 V) is investigated. The correlation between the OCT content and the surface or cross-sectional micromorphology of PO-PIM is also analysed. Under optimised mass transfer conditions, the transmission rules and mechanism of Cr(VI) under an electrodriven membrane extraction system are investigated. Results show that the surface and interior of PO-PIM exhibit micro/nanopores with an OCT content exceeding 50% (w/w). The mass transfer behaviour of OCT to Cr(VI) conforms to the proton coupling mechanism. The voltage drive effectively solves the residue problem of Cr(VI) in the membrane phase, and the permeability coefficient (P) of PO-PIM to Cr(VI) increases with the voltage. The P of PO-PIM to Cr(VI) reaches 43.38 μm·s⁻¹ at 30 V when the OCT content is 82.8% and the feed and stripping phases are pH 2.0 HCl solution and 0.1 mol·L⁻¹ NaOH solution environments, respectively. After the introduction of hydrophobic kerosene into the membrane phase, the stability of the membrane is significantly enhanced. When the composition ratio of kerosene/OCT/PVC is 0.8:2.2:0.5 and the voltage is 30 V, the initial current density rise is only 0.1 A and the pH increases slightly with the repeated use of PO-PIM to four cycles.

Cr（VI）在低压驱动下（0–30 V）通过含1-辛醇（OCT）作为载体和聚氯乙烯（PVC）作为载体的聚合物包合物膜（PO-PIM）从水相的传输行为被调查。还分析了OCT含量与PO-PIM的表面或横截面微观形态之间的相关性。在最佳传质条件下，研究了电驱动膜萃取系统中Cr（VI）的传递规律和机理。结果表明，PO-PIM的表面和内部呈现出微孔/纳米孔，OCT含量超过50％（w / w）。OCT向Cr（VI）的传质行为符合质子耦合机理。电压驱动有效地解决了膜相中Cr（VI）的残留问题，磁导率系数（PO-PIM对Cr（VI）的P）随着电压而增加。当OCT含量为82.8％，进料和汽提相为pH 2.0 HCl溶液和0.1mol·L ^-1 NaOH溶液环境时，PO-PIM在30 V时对Cr（VI）的P达到43.38μm·s ^-1，分别。将疏水性煤油引入膜相后，膜的稳定性显着增强。当煤油/ OCT / PVC的组成比为0.8：2.2：0.5且电压为30 V时，随着PO-PIM的重复使用至四个循环，初始电流密度升高仅为0.1 A，pH值略微升高。
