Abstract In the present work, β-cyclodextrin was grafted to the surface of ZSM-5 via 2,3-epoxypropyl trimethylammonium chloride (ETMAC) and epichlorohydrin (EPI) as the bridging agent by ion exchange and sequential grafting. The mixed matrix membranes were prepared using polyurethane (PU) and ZSM-5 before and after modification. Modified ZSM-5 and corresponding MMM were characterized by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and scanning electron microscope (SEM). These membranes were applied for the removal of phenol from aqueous solution in pervaporation process. The results showed that modified ZSM-5 dispersed homogeneously in polymer. The flux and pervaporation separation index of PU increased greatly with a limited decrease in selectivity by the addition of modified ZSM-5. The increased feed temperature enhanced both the flux and separation factor of PU and modified PU membranes.
