Abstract

Abstract

Fe₃O₄-RGO nanocomposite catalyst was prepared by coprecipitation method and then investigated in Fenton-like process when treating landfill leachate. The effect of reaction time, initial pH value, catalyst mass concentration and H₂O₂ dosage on COD removal rate of landfill leachate were studied. The results indicated that when the initial pH value was 3, catalyst mass concentration was 1 mg/L and H₂O₂ dosage was 0.08 mmol/L, the removal rate of COD removal rate reached a maximum of 64.7% after 90 minutes reaction. The comparison of organic components showed that the macromolecular organic matter in the landfill leachate was well degraded after Fenton-like treatment. The Fe₃O₄-RGO nanocomposite catalyst had good repeatability, and the COD removal rate of landfill leachate was only reduced by 2.3% after 5 times usage.
