Adsorptive removal of Pb(ii) from aqueous solution by novel PES/HMO ultrafiltration mixed matrix membrane

In this work, novel polyethersulfone (PES)/hydrous manganese dioxide (HMO) ultrafiltration (UF) mixed matrix membranes (MMMs) were prepared for adsorptive removal of Pb(II) by varying the weight ratio of HMO:PES in the membrane from 0 to 2.0. The membranes prepared were characterized with respect to...
