Investigation of Anti-Alga Properties and Anti-Bacteria Effects of Composite Nanofiltration Membranes Based on Chitosan Derivatives
J. Miao, H. C. Lin, and L. C. Zhang
Abstract—The anti-alga properties and anti-bacteria effects of composite nanofiltration (NF) membranes prepared from sulfated chitosan (SCS) and N, O-carboxymethyl chitosan (NOCC) were investigated in this study. The base membranes, polyacrylonitrile (PAN) and polysulfone (PS) ultrafiltration (UF) membranes, were used to be as the controls. Compared with the controls, the adsorptions of the alga on the composite NF membranes were less severe. It suggested that the SCS and NOCC composite NF membranes have anti-alga and antifouling abilities. The chosen bacteria were escherichia coli, bacillus subtilis, staureus, penicillium chrysogenum, and streptomyces jinyangensis. By comparing the colony diameters of different bacteria on various membranes and the growth of bacteria after different time periods, the qualitative conclusions of the anti-bacterial effects of the membranes were drawn. It suggested that all the investigated membranes have some anti-bacterial effects on the five kinds of bacteria and the anti-bacterial effects are related to the active layer material of the composite NF membrane and the cross-linking agent.
Index Terms—Composite NF membrane, sulfated chitosan (SCS), N, O-carboxymethyl chitosan (NOCC), anti-alga and anti-bacterial abilities.
