Polymer inclusion membrane (PIM) is a method for separating liquid membranes into thin, stable, and flexible film forms. In this study, the PIM was made using polyvinyl chloride (PVC), dibenzyl ether (DBE), and 4% copoly-eugenol divinyl benzene (co-EDVB) as a supporting polymer, plasticizer, and carrier compound, respectively. Furthermore, a phenol transport test was carried out using the parameters of pH influence, the effect of NaOH concentration, and transport time. The PIM membrane was also evaluated using the parameters affecting the concentration of plasticizer, the effect of salt concentration, and the lifetime of the PIM membrane. The results show that the optimum pH obtained to transport phenol to the receiving phase was 5.5, with a concentration of 0.1 M of the NaOH receiving phase and a transport time of 72 h. Furthermore, it was found that the use of plasticizers and salts affected the ability and resistance of the membranes. The membrane lifetime increased up to 60 days with the addition of 0.1 M NaNO or NaCl salt in the source phase.
聚合物包容膜（PIM）是一种将液膜分离成薄的、稳定的和柔性薄膜形式的方法。在本研究中，PIM分别使用聚氯乙烯（PVC）、二苄基醚（DBE）和4%的共聚丁香酚二乙烯基苯（co-EDVB）作为支撑聚合物、增塑剂和载体化合物制成。此外，使用pH影响参数、NaOH浓度的影响和传输时间进行了苯酚传输试验。还使用影响增塑剂浓度的参数、盐浓度的影响和PIM膜的寿命对PIM膜进行了评估。结果表明，将苯酚传输到接收相的最佳pH为5.5，接收相NaOH浓度为0.1 M，传输时间为72 h。此外，发现增塑剂和盐的使用影响了膜的性能和抗性。在源相中添加0.1 M NaNO或NaCl盐时，膜的寿命延长至60天。
