Filtration of Heavy Metal-contaminated Groundwater Using a Novel Nanofiber Membrane
摘要
Abstract
A novel nanofiber membrane, named M-1, is prepared from chlorinated polyvinyl chloride by high-voltage electrospinning process. The removals of divalent metal cations including Cu2+, Pb2+ and Cd2+ from the simulated groundwater by M-1 have been investigated. To obtain the best heavy metal removal, several filtration methods using M-1 have been presented, including direct filtration, soil-addition filtration, diatomite-addition filtration and micellar enhanced filtration (MEF). The best filtration method for M-1 to remove heavy metal cations is MEF whose optimal experimental conditions are 10-layer filtration and sodium dodecyl benzene sulfonate (SDBS) concentration of 5mmol/L. The experimental results show that the rejections of copper in the simulated groundwater by MEF using M-1 can reach more than 73%;the rejections of lead more than 82%;and the rejections of cadmium more than 91%.关键词
