Abstract—Release of colored textile effluents is undesirable in the aquatic environment as it limits the utilization of the water resources. Photocatalytic decolorization is an alternative method to other conventional inefficient physico-chemical and biological methods to treat toxic effluents. In the present study, the synthesized Calcium zincate nanoparticle (CaZnO2) of average crystallite size 43.59 nm was used as a photocatalyst in presence of sunlight against Coralene Dark Red 2B azo dye (30mg/L). Calcium zincate nanoparticle was synthesized by a simple solution combustion method and characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). Adsorption studies were carried out at different pH, and photocatalyst dosages. The Calcium zincate nanoparticle was found to be an efficient low cost photocatalyst which degraded Coralene Dark Red 2B dye in presence of sun light in a relatively short period of time.
