摘要
研究了硝基苯溶液在石墨和铜电极上的电还原特性,并评价了催化铁内电解还原产物的紫外光谱和电还原特性。结果表明,硝基苯能在铜电极上直接发生得电子还原反应,此即催化铁内电解法反应机理的显著特点。本方法对硝基苯废水进行预处理,是各种化学作用和电化学作用的综合效应,因此,具有较高的处理效率。
Wastewater containing nitrobenzene was treated by electrochemical reduction on cathode; graphite or copper cathode was used. Meanwhile, UV spectrums of reductive products and electrochemical reduction characteristics were investigated. The results indicated that direct reduction of nitrobenzene took place on copper cathode, i.e. the typical catalyzed iron inner-electrolysis characteristics. Nitrobenzene was reduced into aniline before the further degradation.
