Graphene oxide/chitosan doped polysulfone membrane for the treatment of industrial wastewater

Abstract Rapid urbanization and industrialization have created tremendous stress on fresh water sources. Moreover, discharge of industrial wastewater has left public health environment under high potential risks. In this paper, chitosan-functionalized graphene oxide (GO-CH) was synthesized incorporated into polysulfone (Psf) ultrafiltration membranes. The concentration the nanocomposite ratio GO to CH in were varied produce different GO-CH doped effect addition morphology membrane performance studied through contact angle, scanning electron microscopy, atomic force porosity, pore size, permeation measurements as well rejection antifouling tests, while produced characterized using FTIR XRD analyses. GO-CH/Psf exhibited higher flux, bovine serum albumin (BSA) rate, flux recovery ratio, lower BSA solution attenuation rate than pristine Psf membrane. containing 0.085 wt% with 1 0.01 had an improved permeate 136%. Maintaining same composition changing 1:1 resulted better hydrophilicity (contact angle 68°) increased reversible fouling from 23 33%. best further tested real obtained a GTL plant Qatar showed 28% improvement COD removal.
