Enhanced Adsorption of Cr (VI) on Manganese Dioxide - Modified Montmorillonite Composites

Abstract:

Manganese dioxide-modified montmorillonite (MnO₂/MMT), a one-step hydrothermal procedure was utilized for fabricating the composites. The structure, morphology and the particulars of the components were explained by XRD, SEM and BET, which proved that MnO₂/MMT composites were successfully synthesized. Conclusions of the experiment show that the adsorption efficiency of MnO₂/MMT reached 99.63% after 5 hours of adsorption for Cr(VI) solution, which was considerably greater than that of the unmodified montmorillonite under the same conditions. The above study highlights how MnO₂/MMT can be used in the wastewater treatment.
