The elevated level of heavy metals in groundwater poses a substantial risk potentially to local resource users and the natural environment. Micellar-enhanced filtration (MEF) and alumina adsorption are considered from the viewpoint of copper(II) removal in groundwater, by taking copper(II) as an example. In MEF, copper(II) cations are collected electrostatically on micelles of sodium dodecyl benzene...
The morphology, interspace and surface properties of a novel nanofiber membrane are characterized by scanning electron microscopy (SEM), pore percent and contact angle. The membrane, named M-1, is prepared from chloridized polyvinyl chloride by high-voltage electrospinning process. The removals of divalent metal cations including Cu 2+ , Pb 2+ and Cd 2+ from the simulated groundwater...
