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+.

Key words： Metal catalyst Fe2+/Fe3+ Fenton reagents phenol wastewater
