Shao, Jiahui published the artcileHumic acid rejection and flux decline with negatively charged membranes of different spacer arm lengths and charge groups, Formula: C3H6BrNaO3S, the publication is Journal of Membrane Science (2013), 38-45, database is CAplus.
A series of novel charged ultrafiltration membranes that differed in spacer arm length and charge group were generated by covalent attachment of neg. charged group to a com. available regenerated cellulose membrane. Rejection of humic acid and flux decline were compared with essentially neutral and neg. charged versions of regenerated cellulose membranes of different spacer arm lengths and charge groups. Effects of membrane mol. weight cut-off and solution pH on humic acid removal and flux decline on neutral and neg. charged membranes of different spacer arm lengths were also compared. The membrane with larger spacer arm length has better rejection of humic acid and less membrane fouling compared to that with smaller spacer arm length. The modified neg. charged membrane with a strongly acidic (sulfonic acid) functional group has better rejection of humic acid and less membrane fouling than that with a weakly acidic (carboxylic acid) functional group. These exptl. results are consistent with the larger charge of the membranes having larger spacer arm length and sulfonic acid group. This study confirms that the appropriate design of membrane charge functionality could be an effective way for better removal of humic acid and reduction of membrane fouling due to the electrostatic interactions with the combination effect of membrane pore size.
