摘要
采用热氧化法制备Ti/RuO_2-TiO_2-IrO_2钛基氧化物材料,通过SEM、XRD、XRF等方法对制备物形貌和结构进行表征分析,用该涂层材料为阳极,不锈钢为阴极,活性炭颗粒为粒子电极构成电解系统处理亚甲基蓝模拟废水。结果表明,电解时间60 min时,该装置对亚甲基蓝脱色率达到87.83%,COD去除率达到74.45%,脱色率符合表观一级反应动力学规律。将Ti/RuO_2-TiO_2-IrO_2电极与其他常用电极对MB废水的降解效果进行比较分析,该电极对废水脱色率高于其他电极。
A Ti / Ru O2-Ti O2-Ir O2titanium-based oxide electrode was prepared using a thermal oxidation method,and its surface morphology and structure were characterized by scanning electron microscopy（ SEM）,X-ray diffraction（ XRD）,X-ray fluorescence（ XRF）,and other analytical methods. With an electrolytic system using this electrode as the anode,stainless steel as the cathode,and activated carbon particles as particle electrodes,methylene blue simulated wastewater was treated. The results showed that the methylene blue removal rate reached 87. 83%,and COD removal rate reached 74. 45% within 60 min of reaction time. Degradation kinetics study of the wastewater indicated that the methylene blue removal rate followed a pseudo-first-order reaction kinetic model. The removal rate of methylene blue using the Ti / Ru O2-Ti O2-Ir O2 electrode was higher than those obtained using other commonly used electrodes.
