Modification of diatomite was done by impregnating the diatomite surface with 0.35 g of manganese oxide in one gram of diatomite. This modified diatomite was named Mn-Diatomite. The surface area measurements for Mn-diatomite showed a 2.2 fold increase, hence higher removal capacity for the heavy metals. The results of the removal showed an increase in adsorption capacity which was for Pb2+ about 40 mg/g, for Ni2+ about 34mg/g and for Cu2+ about 33mg/g. The filtration quality of diatomite was significantly enhanced with surface modification by manganese oxide.}, keywords = {Diatomite,Mn,heavy metals,Adsorption and Wastewater}, url = {https://www.ije.ir/article_71651.html}, eprint = {https://www.ije.ir/article_71651_dd1ccab688b98f66f027659f0f3c86b5.pdf} }
