NOVELTY - An electrostatic spinning complex nanomembrane is prepared by dissolving polyacrylonitrile (PAN) powder into dimethyl formamide (DMF) solution of graphene oxide (GO), agitating at room temperature for 30-50 hours to obtain uniform transparent PAN spinning solution containing GO, adding in disposable syringe at room temperature, fixing needle head of syringe on supply system of electrostatic spinning equipment, spinning to prepare composite electrostatic spinning composite nanomembrane GO/PAN, adding lead-containing wastewater, and reacting at room temperature and certain pH value, testing concentration of lead ion before and after adsorption, and calculating adsorption amount. USE - Method for preparing electrostatic spinning complex nanomembrane used for removing heavy metal lead ion in wastewater (claimed). ADVANTAGE - The method is simple.
