Degradation of Methylene Blue by Fenton-Like Reaction

Abstract:

In order to enhance the catalytic activity of the heterogeneous Fenton-like reaction, the catalyst of Fe₃O₄ composites was synthesized. The Fe₃O₄ was used as catalyst of the heterogeneous Fenton-like reaction to degrade methylene blue in aqueous solution. The influencing factors, such as pH, initial H₂O₂ concentration, dye concentration and catalyst concentration, were investigated. The results showed that the dye was effectively degraded at pH 3-8. The optimal condition was at pH3.5. The degradation efficiency of dye increased with the increase of the initial H₂O₂ concentration and reached maximum when the H₂O₂ concentration was 15 mmol/L. The degradation efficiency of dye increased with the catalyst concentration was 650 mg/L. The coexisted anions decreased the degradation efficiency of dye.
