| Abstract:Fe/Cu dual active heterogeneous Fenton catalyst was prepared using carbon silicon mesoporous material prepared by acid leaching of coal gasification slag as a carrier through carbon thermal reduction method. The preparation process of the catalyst was optimized and its catalytic effect on the removal of p-chlorophenol and treatment of pulp and paper wastewater by H2O2 was investigated with p-chlorophenol as madel. The results showed that the catalyst prepared under the conditions of calcination temperature of 900 ℃， impregnation solution concentration of 0.2 mol/L， and Fe/Cu molar ratio of 2∶1 had the highest activity， with a removal rate of 96.8% for chlorophenol. Under the conditions of initial pH value=5， H2O2 dosage of 16 mmol/L， catalyst dosage of 1.25 g/L， and reaction time of 120 min， the CODCr removal rate of wastewater was 67.8%， the chromaticity removal rate was 97.4%， and the effluent CODCr was 63.13 mg/L. |
