电化学法降解水中有机污染物具有低碳、高效等特点。本文采用共沉淀法制备Mn/炭黑-泡沫镍电极,通过场发射扫描电镜(FESEM)、X射线光电子能谱(XPS)对电极进行了表征,考察了外加电压、极板间距、电解质浓度和诺氟沙星初始浓度对其降解效果的影响。结果表明,Mn/炭黑-泡沫镍电极可促进·OH的产生,强化电芬顿效果。钛钌—Mn/炭黑-泡沫镍电极在外加电压6 V,极板间距15 mm,电解质浓度20 mmol/L,诺氟沙星初始浓度10 mg/L条件下,诺氟沙星去除率可达83.9%,TOC去除率69.2%,能耗为9.6 kW·h/m3。对比钛钌—泡沫镍电极,在相同条件下,Mn/炭黑-泡沫镍电极的诺氟沙星去除率提高了15.8%,能耗降低了0.6 kW·h/m3并且电流效率提高,反应速率明显加快,表明该电极对抗生素类污染物降解具有较好的催化作用。
