Abstract


The MnO2-modified diatomite was obtained by wet chemical methods. The specific structure of the material has been determined by modern physicochemical methods. The results showed that the surface of diatomite was coated by the manganese oxide nanoparticles. The prepared MnO2-diatomite material is a good adsorbent for the removal methyl orange (MO) in water. The adsorption kinetics of MO on modulation materials are consistent with the pseudo-second-order kinetics model. Therefore, MnO2-modified diatomite materials could be promising sorbents for removing MO.
