The study of pH effect on the formation of thin layer Synthesised by Chitosan-Graft-Acrylamide

For this study, in first suppuort membrane prepared according to previous work and so thin layer chitosan(CS). CS thin layer was prepared with acrylamide and under irradiation microwave. We used TFC membranes that were optimized by three factor concentration acrylamide, time and power irradiation microwave. Therefore, the rejection membrane increases by change in pH of CS solution. The separation properties of thin film composite (TFC) membranes for ion solution (Na2SO4,) were increased and changed by variation of preparation conditions. The main goal of this study is the enhance rejection of CS thin layer on polyethersulfone (PES) UF membrane. Attenuated total reflection-infrared (ATR-IR) apparatus, scanning electron microscopy (SEM), atomic force microscopy (AFM) and nanofiltration set-up were used to characterization and investigation of prepared TFC membranes
