        Cellulose acetate-graft-(glycidylmethacrylate-g-polyethylene glycol) (CA-g- (GMA-g-PEG) was synthesized and incorporated into acetylated methyl cellulose (AMC) to prepare high rejection performance ultrafiltration membranes. H1-NMR and X-ray photoelectron spectroscopy study confirmed the successful synthesis of CA-g-(GMA-g-PEG) and utilized for hydrophilic modification agent. Polyethyleneimine(PEI), HumicAcid(HA) and Citric Acid(CA) ligands was used to bind the metal ions in aqueous solution.The rejection efficiency of AMC/CA-g-(GMA-g-PEG) blend membranes was studied in terms of pH, concentration and time. The successful developments would allow the safe and economical advancement in the fabrication of AMC blend membranes for ultrafiltration applications.
