SYNTHESIS, CHARACTERIZATION AND APPLICATION OF NANOSIO2 AND NANO-PBO IN DYE DEGRADATIONPRIYANKA T. WADITAKE AND PRASHANT L. CHAUDHARIAbstract The precursor solutions were made by mixing Silicon Tetrachloride and Lead chloride respectively for SiO2 and PbO nanoparticles. The detailed Microscopic and Spectroscopic characterizations of the surface morphology for both nanoparticles were conducted by using Ultraviolet Spectroscopy (UV), Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and X-ray Diffraction (XRD). To study the effect of these synthesized nanoparticles, the photo catalytic reduction of harmful azo dye â methylene blue has been investigated using SiO2 and PbO photo catalyst in aqueous solution under irradiation. Experiments were conducted further to check phytotoxicity. These observations indicate that all the two dyes could be degraded completely with similar time intervals. Hence, it may be a viable technique for the safe disposal of textile wastewater into the water streams. |
