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.
