ABSTRACT:
Bi2O3 and Bi2S3 catalyzed photocatalytic degradation of methylene blue dye has been investigated. The effect of various parameters, such as the pH, concentration of dyes, effect of amount of semiconductor and effect of light intensity etc. were observed and discussed. The progress of the photochemical oxidation was monitored spectrophotometrically. The optimum reaction conditions were experimentally determined. The photochemical oxidation of dyes follows pseudo – first kinetics. The final products of degradation were characterized and a tentative mechanism was proposed for the photochemical oxidation of dyes.
