SYNTHESIS OF NANOSCALE MAGNESIUM OXIDE - Delonix regia AND MANGANESE OXIDE - Delonix regia COMPOSITES AND THEIR COMPARATIVE STUDY OF ADSORPTIVITY ON METHYLENE BLUE

摘要

Nanoparticles of Magnesium Oxide and Manganese Oxide were synthesized by a chemical method and coated on Delonix regia-activated carbon separately. The composites were characterized by different methods such as Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD) and Energy Dispersive X-Ray Analysis(EDAX). Batch mode of experiments of Methylene blue dye removal was carried out. The adsorption capacity of Methylene blue dye of nanocomposite of magnesium oxide was observed higher than the nanocomposite of manganese oxide.
