Separation of heavy metals from water samples using anion exchange polymers by adsorption process

► A novel QAPSEBS membrane has been successively prepared. ► The modification on the polymer has been characterized by FT-IR and 1H-NMR. ► TGA and DSC showed membrane has better capability to work in adsorption process. ► Adsorption process has been successively applied for removal of Cu(II), Ni(II) and Cr(VI) ions.
