Azo dyes present in textile wastewater require a proper technique for their removal, due to their negative environmental and health effects. Although there are several ways to treat such wastewater, this study is focused on photocatalytic degradation on Calcium Zinc Aluminate (CaZnAl2O5) nano catalyst. Violet GL2B (VGL2B) dye was used for photocatalytic degradation studies at 30 mg/L concentration. Colour degradation was monitored using UV-Vis spectroscopy. Complete colour removal was observed for the azo dye. It is found that, degradation rate of VGL2B for CaZnAl2O5 the degradation was found to be 99.07% at pH 4 in 120 minutes for 0.6g/100ml. Also the results revealed that, the degradation facility is directly bear upon by the concentration of dye solution.
