Application of nano particles Fe3O4, -Fe2O3 and - Fe2O3 remove ions of heavy metals from contaminated water

One of the main problems of surface and underground water hazardous concentrations of heavy metals into the precious resources that are. The method this type of filtration to remove contaminants such that is used to capture the mentioned surface. In adsorption sorbent surface area and volume due to the high porosity is able to absorb pollutants and water to separate into their cavities. Because the surface area and volume of porous iron particles having a substantial ability to absorb pollutants from the water able to be. The ability of nano particles - Fe2O3Fe3O4، and -Fe2O3 ion in the adsorption of heavy metals such as Cr6 +، Cu2 +، C 2 + and Ni2 + studied and compared.
