Abstract
An m-aramid/cellulose blend membrane for nonpressure driven filtration was prepared. The m-aramid/cellulose solution in DMAc/LiCl was thin layered on a glass plate and then dipped into a coagulation medium. Scanning electron microscopy was used to examine the morphology of the m-aramid/cellulose blend membranes. The liquid permeability of the m-aramid/cellulose blend membranes was determined using capillary flow porometry. LiCl in a water/DMAc coagulation medium resulted in an enhancement of the average pore size of the m-aramid/cellulose blend membranes during coagulation. The chlorinated m-aramid/cellulose membrane disinfected bacterial solutions of both Escherichia coli and Staphylococcus aureus to a much higher degree than that observed for the unchlorinated m-aramid/cellulose membrane.
