Synergetic Degradation of Enzyme-Fenton Reagent for Methyl Orange

Abstract:

The effects of pH adjustment method, pH value, UV light, catalase and Fenton reagent on the degradation efficiency of enzyme-Fenton reagent for methyl orange (MO) were investigated, and the synergetic catalytic effects of catalase and Fenton reagent on the catalytic oxidation for methyl orange were found. When under no UV-light, the enzyme can enhance the degradation efficiency of Fenton reagent. The optimum conditions for degrading methyl orange simulated wastewater whose concentration is 0.1 g/L at room temperature are obtained as follows: the pH is tuned with H₂SO₄, pH is 3.0, concentration of catalase is 5 μg / mL, concentration of H₂O₂ is 0.01%, concentration of FeSO₄ is 1.8μmol / L. The degradation rate can reach 98% in 60min. When under UV light at the same condition, the degradation rate can reach 94% in only 15min.
