The Removal Of Phenol From Synthetic Wastewater Using ‎calix[4]resorcinarene Derivative Based Polymer Inclusion ‎membrane

In the present study, the removal of phenol from synthetic ‎wastewater across polymer inclusion membrane (PIM) containing ‎calix[4]resorcinarene derivative used as a carrier were ‎investigated. Phenol removal showing high efficiency when ‎transported through PIMs prepared from cellulose triacetate (CTA) ‎as a polymeric support material and 2-NPOE as a plasticizer. The ‎effects of membrane composition, type of plasticizer, carrier ‎content, pH phase’s solution, and membrane stability, were ‎examined in the facilitated transport experiments of phenol across ‎PIM. A PIM containing 0.1 g CTA, 0.15g/g CTA of carrier and 1.5 ‎g/g CTA of NPOE, provided the highest percentage of phenol over ‎‎5 days of transport, the feed solution in these transport experiments ‎was at pH 2, while the stripping solution contained 0.25M NaOH. ‎The prepared PIM were characterized by using Fourier transform ‎Infra Red (FTIR), XRD and Thermo gravimetric analysis (TGA) ‎techniques. ‎
