Abstract:
Mixed matrix polyethersulfone (PES) based nanofiltration membrane was prepared through phase inversion method by using of polyvinylpyrrolidone (PVP) as pore former and N, N dimethylacetamide (DMAc) as solvent. Polyaniline-grafting-graphene oxide nanoplates (PANI-g-GO) were utilized as additive in membrane fabrication. The PANI/GO nanoplates were prepared by polymerization of aniline in the presence of graphene oxide nanoplates. Scanning electron microscopy (SEM), water contact angle test, water content tests, salt rejection and flux tests were used in membrane characterization. SEM images also showed formation of wide pores for the modified membranes. Water flux showed constant rend nearly by using of PANI/GO in the casting solution. Opposite trend was found for the membrane surface hydrophilicity. The salt rejection was enhanced sharply by utilizing of PANI/GO. The water content was increased initially by utilizing of PANI/GO nanoplates up to 0.05 %wt into the casting solution and then decreased
