Abstract:
ABSTRACT The present study reports preparation of nano sized MnO2 for the adsorptive removal of environmentally hazardous malachite green (MG) dye. MnO2 nanoparticles were prepared by facile solution combustion synthesis using Mn(NO3)2 and urea as oxidizer and fuel respectively at a low temperature of ~ 400 oC. Phase formation of the prepared sample was analyzed with powder X-ray diffraction (PXRD) studies, scanning electron microscopy (SEM). The PXRD results confirm partial crystallinity and cubic phase and crystallite size of the MnO2 was calculated using Debye- Scherer’s formula and it is found to in the range of 25-40 nm. SEM images show the formation of nearly spherical and agglomerated particles. Optical energy band gap was calculated using UV Vis spectroscopy. Adsorption of MG dye onto the MnO2 nanoparticles studies were performed with various parameters such as effect of adsorbent dosage, contact time, initial concentration of the dye and pH of the pollutant. The results suggest that the MnO2 nanoparticles are excellent adsorbent for the removal of MG dye. Keywords:- Nano MnO2, Solution combustion, Malachite green, Adsorption.
