Abstract

Abstract

The sol-gel method was used to prepare the Fe/Cu/zeolite catalyst for heterogeneous Fenton oxidation. The reaction conditions of catalytic degradation of benzotriazole in water at neutral pH were optimized, and the reusability of the material was investigated. Finally, the mechanism of catalytic oxidation degradation of BTA was discussed. The results showed that Fe and Cu nanoparticles in the catalyst were uniformly distributed on the surface of the zeolite particles, and the main components were Fe₂O₃, Fe₃O₄ and CuO. Under neutral pH conditions, the highest degradation rate of benzotriazole was achieved at the concentration of H₂O₂ 0.08 mol/L, the catalyst dosage 0.41 g/L and the reaction time 43.6 min. During the catalytic degradation process, Fe and Cu participate in the Fenton reaction to generate ·OH radicals, and achieve efficient removal of pollutants.
