In present work, a photocatalytic degradation of Erythrosin-B has been studied using cadmium cobaltite. The impact of different parameterssuch as pH, amount of cadmium cobaltite, concentration of Erythrosin-B and light intensity have been observed on the reaction rate.Radical quenching experiments revealed that hydroxyl radicals are primarily responsible for the degradation of Erythrosin-B. The progressof reaction monitored spectrophotometrically and it followed pseudo first-order kinetics. An experimental mechanism is proposed for thephotochemical degradation of Erythrosin-B.
