作者（2019）在《Study on CeO2/CuFe2O4 Catalytic Ozonation of Resorcinol》一文中研究指出：In order to improve the catalytic ozonation effect of resorcinol, the spinel CuFe2O4 was modified by doped CeO2, and X-ray diffraction（XRD） and scanning electron microscopy（SEM） were used for characterization analysis. The effects of composite catalyst CeO2/CuFe2O4 dosage, ozone dosage, initial pH and reaction temperature on degradation were studied, and the stability of the catalyst was tested. The results showed that the composite effect of CeO2/CuFe2O4 prepared by combustion method was good, and the catalyst presented a laminated structure, in which 30 wt% CeO2/CuFe2O4 degradation effect was significant. The removal rate of resorcinol using CeO2/CuFe2O4 composite catalyst was higher than that using ozone or CuFe2O4 separately by 41.8% and 11.9%, respectively. In a reaction with resorcinol concentration of 100 mg/L, the catalyst dosage of 1.0 g/L, the ozone dosage of 2.5 mg/（L·min）, at pH=9, temperature of 20 ℃, for reaction time of 40 min, the resorcinol removal rate was 88.5%. The catalyst CeO2/CuFe2O4 still showed good degradation effect after repeatedly using for 10 times, and the dissolution rate of metal ions was lower than that of CuFe2O4.
Abstract
In order to improve the catalytic ozonation effect of resorcinol, the spinel CuFe2O4 was modified by doped CeO2, and X-ray diffraction（XRD） and scanning electron microscopy（SEM） were used for characterization analysis. The effects of composite catalyst CeO2/CuFe2O4 dosage, ozone dosage, initial pH and reaction temperature on degradation were studied, and the stability of the catalyst was tested. The results showed that the composite effect of CeO2/CuFe2O4 prepared by combustion method was good, and the catalyst presented a laminated structure, in which 30 wt% CeO2/CuFe2O4 degradation effect was significant. The removal rate of resorcinol using CeO2/CuFe2O4 composite catalyst was higher than that using ozone or CuFe2O4 separately by 41.8% and 11.9%, respectively. In a reaction with resorcinol concentration of 100 mg/L, the catalyst dosage of 1.0 g/L, the ozone dosage of 2.5 mg/（L·min）, at pH=9, temperature of 20 ℃, for reaction time of 40 min, the resorcinol removal rate was 88.5%. The catalyst CeO2/CuFe2O4 still showed good degradation effect after repeatedly using for 10 times, and the dissolution rate of metal ions was lower than that of CuFe2O4.
