A COMPARATIVE STUDY IN PHOTOCATALYTIC DEGRADATION OF COOMASSIE BRILLIANT BLUE G DYE BY USING NICKEL CALCIATE NANOPARTICLES

The photodegradation efficiency of two synthesized Nickel Calciate nanoparticles (NiCaO2-I and NiCaO2-II) against Coomassie Brilliant Blue G (CBBG) dye in aqueous solution was investigated. The Nickel Calciate nanoparticles were synthesized by solution combustion method using two different fuels urea and acetamide. The synthesized nanoparticles were characterized by SEM, XRD, EDX and the band gap was determined by using UV-absorption spectroscopy. All the experiments were conducted in presence of natural sun light. Degradation efficiency was studied by varying different parameters such as catalyst concentration, solution pH, dye concentration and in different conditions with respect to UV and dark conditions
