摘要

以活性炭为载体,通过浸渍法制备了CuO/AC粒子电极,采用XRD、SEM、EDS等方法对粒子电极的理化性能进行了表征,并通过荧光测定粒子电极对于羟基自由基的生成能力。结果表明,CuO负载于粉末状活性炭表面,提供了更多的电化学活性位点;CuO的引入,增强了粒子电极的羟基自由基生成能力。考察了CuO/AC粒子电极电催化氧化处理活性艳蓝KN-R模拟废水脱色性能。CuO/AC粒子电极对目标污染物活性艳蓝有着良好的电催化氧化性能。在反应时间为1 h时,CuO/AC粒子电极的脱色率(87.2%)比AC粒子电极(64.6%)提高了22.6%,且可多次循环利用。
        CuO/AC particle electrode was prepared by impregnation method. The physical and chemical properties of the particle electrode were characterized by XRD, SEM and EDS. The generation capacity of hydroxyl radical by the particle electrode was measured by fluorescence. The results showed that CuO loaded on the surface of powdered activated carbon provided more electrochemically active sites. The introduction of CuO could enhance the ability of the particle electrode to generate hydroxyl radicals. Electrocatalytic oxidation treatment of simulated wastewater with three-dimensional electrode method was also carried out. The performance of CuO/AC particle electrode was investigated. CuO/AC particle electrode showed good electrocatalytic activity and stability to target pollutant reactive brilliant blue. The decoloration rate of CuO/AC particle electrode(87.2%) was 22.6% higher than that of AC particle electrode(64.6%) at the experimental time of 1 h, and it could be recycled for many times.
