| 摘 要： | 采用电沉积法制备了Ti基PbO2电极(Ti/PbO2)和Ce改性Ti基PbO2电极(Ti/PbO2—Ce).利用扫描电子显微镜(SEM)和循环伏安法对改性前后的电极进行表征,并考察电极的电催化氧化能力.实验结果表明:Ti/PbO2—Ce电极具有比Ti/PbO2电极更小的晶粒尺寸和更高的电催化氧化降解有机物污染物能力.Ti/PbO2—Ce电极电催化氧化降解4—氯酚(4—CP)2 h后,溶液的BOD5/COD值由0.03升高到0.48,有效地提高了4—CP废水的可生化性.

| Abstract: | In this study,Ti based PbO2electrode（Ti/PbO2） and Ti based PbO2electrode modified with Ce（Ti/PbO2-Ce） were prepared by electrodeposition method. Scanning electron microscope（SEM） and cyclic voltammetry（CV） were used to characterize the electrodes. Furthermore,the electro-catalytic oxidation performance of electrodes was measured. The results showed that Ti/PbO2-Ce electrode had finer crystal and higher degradation capacity of organic pollutants than Ti/PbO2electrode. After degradation of 2 h of 4-CP,the BOD5/COD value of 4-CP degradation solution increased from 0. 03 to 0. 48,and the biodegradability of 4-CP wastewater was improved effectively. |
