Heavy metals are commonly associated with introducing pollution and toxicity into the atmosphere and environments. There are numerous physical and chemical treatments, including adsorption and chemical precipitation, for removal of heavy metals from wastewater. The techniques are mainly expensive with low selectivity. Another option for separation of heavy metals from wastewater is membrane technology. High performance may be .obtained by integration of membranes with the existing plants or membrane modification In current work, PES+PVDF/PVA/Fe3O4 nanocomposite membrane containing 8 Hydroxyquinoline (as a chelating agent) was prepared to obtain a new mixed matrix membrane with the enhanced affinity for lead ions.
