  • 摘要: 通过实验探究了不同Ru掺杂量对 Ti/Ru/SnO2+Sb2O5电极电化学性能及表面结构的影响。结果表明:Sb含量10%,溶胶涂覆6层,煅烧温度600 ℃,煅烧时间1 h条件下,Ru掺杂量为10%的涂层电极的加速寿命最长,为50 min;该条件下制备的电极涂层表面金属氧化物 SnO2的特征峰强度较大,峰形窄;涂层表面光滑,无裂缝。同时用Ti/Ru/SnO2+Sb2O5电极处理垃圾渗滤液MBR出水,Ru掺杂为10%的电极对废水COD去除率最高,为93.33%,电解出水芳香化程度大幅降低,对腐殖质和芳香族化合物的去除效果良好。研究对Ti/Ru/SnO2+Sb2O5电极在实际工业生产中的应用具有指导意义。
