【摘要】 采用钛基锡锑（Sn-Sb/Ti）电极作为氧化阳极,不锈钢为阴极,电催化氧化降解废水中硝基苯。实验结果表明,处理硝基苯废水的最佳条件为:电流密度25 mA/cm²;Na₂SO₄作为电解质,加入量15g/L;极板间距2 cm;溶液初始pH 6。在此最佳条件下,硝基苯去除率大于95%,TOC去除率大于80%,表明Sn-Sb/Ti阳极能有效去除废水中有机污染物。更多还原

【Abstract】 Nitrobenzene in wastewater was degraded by electrocatalytic oxidation using Sn-Sb/Ti electrode as anode and stainless steel as cathode.The experimental results show that the optimum treatment conditions are as follows:current density 25 mA/cm²,electrolyte Na₂SO₄ dosage 15 g/L, distance between anode and cathode 2 cm,initial solution pH 6.Under the conditions,the removal rates of nitrobenzene and TOC are above 95%and 80%respectively,which indicate that the Sn-Sb/Ti anode can effectively remove organic pollutants from wastewater.更多还原
