Removal of Organics from Landfill Leachate by Heterogeneous Fenton-like Oxidation over Copper-Based Catalyst

Landfill leachates are a mixture of high concentration organic and inorganic contaminants need to be appropriately treated due their toxicity severe adverse effects on the environment. Here, we studied treatment landfill leachate through heterogeneous Fenton-like oxidation process using zirconia supported copper catalyst (Cu/ZrO2). Reaction conditions such as pH, amount catalyst, oxidant dose, temperature, reaction time were investigated pollutant abatement discussed. AOS (average state) COS (carbon parameters used for evaluation degree process, obtaining some insight into formation oxidized intermediates (partial oxidation) total (mineralization) during reaction. A two-step enhanced overall performance with an compounds 92% confirming promising activity copper-based liquid waste. Higher catalytic was achieved when following applied: 70 °C, pH 5, 200 mg/L 30 mL/L H2O2 150 min. In addition, durability under optimized verified by repeated cycles.
