Thin film composite (tfc) membranes : effects of monomer and solvents in interfacial polymerization process for dye removal

Abstract

Thin film composite (TFC) membrane consists of a very thin film which is formed on top of a porous support and commonly made of polysulfone (PSF) where the active layer is an aromatic crosslinked polyamide (PA) film. Hence, PA TFC membranes cause higher water flux and rejection of ion and organic compared to CA membranes. In this study, the effects of different monomers and solvents towards performance of TFC membranes in salt rejection and dyes removal were investigated. TFC membranes were synthesized directly from interfacial polymerisation aromatic polyamide. The preparation condition of TFC membranes are studied with reference to different monomer of trimesoyl chloride (TMC) and solvents of hexane and cyclohexane.
