High efficient removal of lead(II) and nickel(II) from aqueous solution by novel polysulfone/Fe3O4–talc nanocomposite mixed matrix membrane

Novel mixed matrix membranes were prepared from polysulfone (PSf), talc and Fe3O4–talc nanocomposite by phase inversion technique. PSf/Fe3O4–talc membranes showed higher lead and nickel rejections compared to PSf/talc membranes, which reaches to 99.4 and 96.2% for lead and nickel ions, respectively,...
