摘　　要：利用刷涂法制备了Ti/SnO2-RuO2电极,并通过SEM、XRD等测试手段对其进行形貌及结构表征。利用该电极为阳极处理黑索金(RDX)废水,考察了电解质种类、电解质质量浓度、废水pH、电流密度以及电解时间等对RDX电催化氧化效果的影响。实验结果表明,当处理100 mL质量浓度为50 mg/L的RDX废水时,以Na2SO4为电解质、Na2SO4质量浓度为5.0 g/L、废水pH为7、电流密度为15 mA/cm2、电解时间为300 min的条件下,RDX去除率达到82.55%,COD去除率达到55.41%。Ti/SnO2-RuO2 electrode was prepared by brush coating method, and its morphology and structure were characterized by SEM and XRD. Hexogen （RDX） wastewater was treated using the Ti/SnO2- RuO2 electrode as anode, and the factors affecting the electro-catalytic oxidation of RDX were studied. Under the conditions of wastewater volume 100 mL, RDX mass concentration 50 mg/L, wastewater pH 7, Na2SO4 （electrolyte） mass concentration 5.0 g/L, current density 15 mA/cm2 and electrolysis time 300 min, the removal rates of RDX and COD are 82.55% and 55.41% respectively.
