Abstract: The cellulose acetate (CA) microporous membranes weremodified by chemical surface-grafted method with anionic polyacrylamide.The effects of concentration of anionic polyacrylamide and cross-linking agent,reaction time and temperature on grafting yield and the flux and rejection of graftedmembrane were investigated.The results show that the flux of modified membranesdecreased while the rejection increased with increasing concentration of anionicpolyacrylamide and cross-linking agent,extending reaction time,raising reaction temperature.

Key words: chemical surface-grafted method, anionic polyacrylamide, microporous cellulose acetate membrane
