Abstract

Abstract

The aim of this study was to enhance the typical refractory organics degradation in the wastewater treatment by using A Fenton-like catalyst, which was synthesized and tested for the antipyrine and dyes degradation. The results demonstrated that the metallic oxide catalyst, Cu_1-xCo_xFe₂O₄ prepared by the hydrothermal method had a good crystal structure with the specific surface area of 147.3~187.5 m²/g, and the saturation magnetization value of 17.2~62.3 EMU/g. With the Co content increasing, the catalytic activity of the catalysts increased significantly. The optimized catalyst of Cu_0.25Co_0.75Fe₂O₄ had the applicable pH range of 7~9. With the initial antipyrine concentration of 50 mg/L, the catalyst dosage of 0.7 g/L and H₂O₂ dosage of 150 mmol/L, the antipyrine removal reached 93.1% at the initial pH=7 and 94.7% at the initial pH=9, respectively. Different types of refractory organic compounds, such as rhodamine B and acid orange Ⅱ, could also be effectively degraded with the catalyst. After 5 cycles of magnetic recovery and reuse of the catalyst, the antipyrine removal could be kept 80% above, indicating that the catalyst had good stability and reusability. The Fenton-like catalyst synthesized in this study provided scientific basis for efficient removal of refractory organic compounds from wastewater.
