摘要：A polymer inclusion membrane (PIM) system containing polyvinyl chloride (PVC) polymer matrix and bis(2-ethyl hexyl)-phosphoric acid (D2EHPA, P204), as a specific carrier, was prepared without using any additional plasticizers, expressed as PD-PIM. The chemical composition, crystallization behavior and morphology of as-prepared PD-PIM were characterized with Fourier transform infrared spectrophotometry, X-ray diffraction and atomic force microscopy. The facilitated transport of phenol through the PD-PIM was investigated. The influences of carrier content of PD-PIM, phenol concentration, pH in source phase, and HCl concentration in receiving phase on the transport were investigated. The transport kinetics of phenol and the stability of membranes were studied. The results show that the early transmission process of phenol is in line with the first order kinetic equation and the optimal transport process can be obtained with the membrane containing 70% D2EHPA/30%PVC (mass), from the source solution of phenol concentration at 400 mg·L-1 and pH 6.0, by using 0.1 mol·L-1 HCl as receiving phase. In addition, the experiments demonstrate that PD-PIM presents good stability and the phenol transport through the membrane is facilitated by co-transport.
