dc.description.abstractThe photocatalyst BaCrO4 has been utilized to photocatalytically degrade Azur B in presence of visible light. The disappearance of the dye has been monitored spectrophotometrically, followed pseudo-first order kinetics, according to the Langmuir–Hinshelwood model. The total degradation of dye was tested by determining the chemical oxygen demand. To optimize the reaction condition, the effects of various parameters like amount of semiconductor, pH, light intensity, dye concentration, oxidants such as H2O2 and K2S2O8, electron acceptors like NaCl and Na2CO3, on the rate of photodegradation have been investigated. Both NaCl and Na2CO3 are found to retard the rate of photocatalytic degradation, whereas increase in the initial concentration of both H2O2 and K2S2O8, increases the degradation rate. The degradation efficiency was found to be the substantially high at around neutral pH values. The complete degradation of the dye has been confirmed using UV spectrum analysis. A pertinent mechanism for the photocatalytic degradation has also been proposed. en_US
