摘要：
Experimental results on a study on removal of metal ions using lecithin-enhanced dead-end filtration with 0.1 micron nylon membrane has been reported in this paper. The effects of metal-ion concentration on the pH, conductivity and zeta potential of lecithin dispersions were determined. The zeta potential of lecithin was determined to be -79 mV whilst the critical micelle concentration was 9 g.l(-1). Significantly, the study showed that lecithin has the ability to adsorb metal ions. This study gives an alternate technology for metal ion removal from aqueous solutions.
