Dyes are easily soluble in water by imparting its color, which leads to the water pollution in large sector by the industries to river. Purification of polluted water is not possible in the water bodies which are not economically suitable, with the literature survey series of nanoparticles have used for the degradation, later these nano particles forms toxic to the aquatic system. However to overcome from this issue, the newly synthesized calcium oxide nanoparticles are subjected for photo degradation of different synthetic dyes in lab condition, which are harmless and sediment. The nanoparticles had well calcinated and characterized by SEM and powdered X- ray diffraction. In series some dyes showed good results with complete degradation. The comparative study reveals the complete degradation of dyes.
