Heavy metals are among the environmental pollutants which humans can encounter through water and food Cause dangerous chronic and acute poisoning. Water pollution with heavy metals, an existing and evolving problem is in the world. Heavy metals such as lead, copper, cadmium, zinc and nickel, Are among the most common pollutants in Industrial wastewater is found [1]. Various methods for removing heavy metals from solutions is used, including ion exchange, Adsorption, reverse osmosis, electrodialysis, concentration evaporation, Bio removal, solvent extraction, clotting and separation process Constantly pointed. Currently for economic and technical reasons, these methods are often not accepted in the country and abroad [2]. Among the adsorbents, graphene oxide nanoparticles due to their potential high absorption capacity and high specific surface area for removal heavy metals are used from water [3].
