Ferrous Ion Catalyzed Photooxidation of Methylene Blue with Peroxydisulphate Ion

Authors(4) :-Jyoti Soni, Anil Chohadia, Narendra Nirwan, Kumud Intodia

Photooxidation of dyes is a new concern among researchers since it offers an attractive method for decolorization of dyes and breaks them into simple products. Photochemical oxidation of methylene blue (MB) was investigated in presence of Fe+2 and peroxydisulphate ions at normal temperature and pressure. The effect of operating variables like the concentration of ferrous ions, concentration of methylene blue, pH, and concentration of peroxydisulphate ion and light intensity on the rate of reaction was also observed. The progress of the reaction was monitored spectrophotometrically. The photochemical oxidation of dye follows pseudo first order kinetics. The results showed that the methylene blue was completely oxidized and degraded into CO2 and H2O. A suitable tentative mechanism for photochemical oxidation of methylene blue has been proposed.
