摘要
通过循环伏安法和缓冲电解研究了酸性条件下对硝基苯酚在掺硼金刚石膜电极上的电化学氧化,结果表明:电解试验发生了多种氧化反应矿化对硝基苯酚.在电解过程中检测到多种可溶性产物如对苯二酚、对苯醌、草酸等.这一结果说明:氧化对硝基苯酚,首先是硝基脱离苯环生成酚类物质,然后转化为羧基酸,最后氧化为二氧化碳.
The electrochemical oxidation of 4-nitrophenol has been studied on boron-doped diamond electrodes on acid medium by cyclic voltammetry and bulk electrolysis. The results showed complex oxidation reactions that lead to incineration of 4- nitrophenol. Hydroquinone, p-benzosemiquinone, maleic, and oxalic acid have been detected as soluble products during the electrolysis of 4-nitrophenol. These results suggest that the electro-oxidation of 4-nitrophenol begin by the release of nitro groups from the aromatic ring to form non-nitrogenated phenolic compounds. These compounds are transformed into carboxylic acids which end to be oxidized to CO2.
