Abstract:Based on the analysis of Fenton oxidation mechanism, the influence of metal catalyst Fe2+/Fe3+ on activity of?Fenton reagent was studied. The results show that, Fe2+ and Fe3+ both have?catalytic effect on the activity of?Fenton reagent, and Fe2+ has more catalysis than Fe3+. The removal rate of wastewater COD in coking phenol reaches 90.2% (mass percent) with the H2O2 dosage of 12 mmol/L,?reaction temperature of 25 ℃, reaction time of 25 min, and the molar ratio of [Fe2+]/[H2O2] is 1∶10. The activity of Fe2+ and Fe3+ increases with synergistic effect of light, especially ultraviolet ray. The enhancement tendency of Fe3+ is significantly higher than that of Fe2+.
