Abstract
Zirconium oxide with the tetragonal phase was prepared from zirconium nitrate and urea by solution combustion method. Nano-photocatalyst zirconium oxide was investigated by XRD, SEM-EDAX, TEM, UV absorbance spectroscopy and specific surface area analysis. The distribution size of ZrO was found to be less than 17nm and was confirmed by XRD and TEM studies. Further the ZrO nano-photocatalyst confirms the tetragonal phase by XRD. EDAX reveals the formation of ZrO. The efficiency of ZrO nanoparticles in the photodegradation of victoria blue B and acridine orange dye under sunlight was investigated. The results reveal that the degradation efficiency was found to be 95.42% for VBB (at 0.030g/pH 6/1×10−4mol/dm3) and 92.52% for AO (at 0.035g/pH 4/1×10−4mol/dm3). Further the degradation efficiency shown highest in VBB dye when compare to AO dye. Therefore, the ZrO nanoparticle has been found to be suitable for the treatment of textile effluents.
