Abstract

 Research on PHOTOCATALYTIC DEGRADATION rate of AZO DYES using nano STRONTIUM TITANATE in photocatalysis process was the main goal of present study. In this regard, the influence of the main operating parameters such a photo-catalyst concentration, dye concentration, temperature, pH and auxiliary hydrogen peroxide upon dye removal rate under UV IRRADIATION were studied. Dye absorption measured by a UV-Vis spectrophotometer. The structure and morphology of nano powder were investigated using scanning electron microscopy and crystallinity by X-ray diffraction spectroscopy. The results reveal that nano STRONTIUM TITANATE has high and significant photocatalytic activity and in comparison with nano-titanium dioxide was superior photo-catalyst.
