Abstract
In the present study, a novel membranes were developed from tea filter bag as a base substrate which was subsequently coated by a casting solution containing polyvinylidene fluoride (PVDF) blending and addition of MIL-101 (Cr) metal-organic framework (MOF)- molecularly imprinted resorcinolformaldehydemelamine (MIRFM) as filler was prepared by phase inversion technique (PVDF/MIRFM). The MIRFM contains selective functional groups was used as filler in the adsorptive membrane. The as-prepared filler and mixed matrix membranes (MMMs) were characterized by FE-SEM, XRD, FTIR, BET and water contact angle (WCA). The filtration of Erythrosin B (EB) on the PVDF/MIRFM membranes were studied through investigating the parameters such as the mass of PVDF, filler and volume of Triton x-405 in a cross-module filtration setup. Casting solution containing of MIRFM demonstrated good wettability, high water flux, porosity (87.7%), flux recovery ratio (74.1%) and EB removal efficiency (91.5%). Results indicated that appropriate of MIRFM in membranes could be an effective and selective way for EB removal.
