Optimization of the catalytic wet peroxide oxidation of phenol over the Fe/NH4Y catalyst
The heterogeneous NH4Y zeolite-supported iron catalysts were prepared by incipient wetness impregnation.The catalysis oxidation degradation of phenol was carded over the heterogeneous catalyst in the peroxide catalytic oxidation process.Compared with the homogeneous Fenton process,the Fe/NH4Y-acid catalyst can effectively degrade contaminants with high catalytic activity and easy catalyst separation from the solution.The phenol removal efficiency could reach 96% in the optimum experimental conditions.These process conditions were as follows:iron content is 5%,reaction time was 60 min,reaction temperature was 70 ℃,the catalyst dosage was 1g/L,the H2O2 concentration was 1.65g/L.
