| 摘 要： | 本文研究了两种电极材料 (SnO2 Ti和RuO2 Ti)对酸性红B模拟废水的脱色效果 ,考察了不同 pH、电流密度(j)及外加电解质 (Na2 SO4/NaCl)对处理过程的影响。结果表明 ,两种电极材料都能对酸性红B染料废水进行有效脱色 ,主要是Cl-在电解过程中的间接氧化作用 ,同时也包括电极表面的直接氧化作用。

| Abstract: | Decoloration of acid red B (ARB) synthetic wastewater at SnO 2 Ti and RuO 2 Ti anodes was investigated. The effects of pH, current density and supporting electrolyte (Na 2SO 4/NaCl) were studied. It showed that efficient decoloration was achieved at both anodes. The process was mediated by active chlorines generated by electrochemical oxidation of chlorine ions as well as by direct electrochemical oxidation at the anode surface. |
