Ti/Ru/SnO2+Sb2O5电极的制备及其对垃圾渗滤液的电催化氧化

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。

Preparation of Ti/Ru/SnO2+Sb2O5 electrode and electrocatalytic oxidation of landfill leachate

The effects of different Ru doped quantities on electrochemical properties and surface structures of Ti/Ru/SnO2+Sb2O5 electrode were investigated in this experiment. The results show that the electrode has a longer accelerated life under the condition of 10% Ru doped, 6 coating layers, 600 ℃ calcination temperatures and 1 h burning time. Under these conditions, the characteristic peak intensity of SnO2 is higher and narrower. The coating surface of electrode is smooth and no cracks. When treating MBR effluent of landfill leachate with the electrode under the condition of 10% Ru doped, the removal rate of COD was 93.33%, and the aromaticity can greatly reduce. Humus and aromatic compounds also can be reduced under this doped contents.
