- Abstract:
- The performance and kinetics of Fenton advanced oxidation process for odorous compound 2, 3, 6-trichloroanisole degradation in water were investigated, the effects of solution pH, molar ratio of Fe2+ and H2O2, Fe2+ concentration and reaction time on the degradation of 2, 3, 6-trichloroanisole were discussed, and the optimum conditions for the degradation of 2, 3, 6-trichloroanisole were determined. When the reaction conditions were as follows: solution pH of 3.0, molar ratio of Fe2+ and H2O2 of 1∶136, Fe2+ concentration of 16 mg/L and the reaction time of 10 min, Fenton oxidation effectively degraded 2, 3, 6-trichloroanisole in water with an removal efficiency of 91.6%. The degradation of 2, 3, 6-trichloroanisole by Fenton advanced oxidation process conformed to quasi-first-order kinetics, and the reaction rate constant decreased with the increase of the initial concentration of 2, 3, 6-trichloroanisole. Fenton oxidation for the degradation of 2, 3, 6-trichloroanisole was dominated by dechlorination, and the intermediate product was dichlorophenol. Therefore, Fenton advanced oxidation is an effective process to deal with the pollution of 2, 3, 6-trichloroanisole in water.
