【摘要】 本文在不同电极(Ti/PbO2,Ti/Ru-Ti-Sn)上研究了苯酚羟基化和苯酚溶液的电化学氧化反应。用Uv-vis光谱研究了不同电极对苯酚的电化学氧化及其中间产物的影响,通过高效液相色谱(HPLC)方法检测了不同电极上羟基自由基的产生和存在。研究结果表明,电极上羟基自由基的电化学生成导致苯酚的羟基化,苯酚溶液的降解是羟基化产物(对苯二酚、邻苯二酚)进一步氧化的结果。更多还原

【Abstract】 The hydroxylation reaction of phenol and the electrochemical oxidation in phenol aqueous solution was studied on different electrode material (Ti/PbO2, Ti/Ru-Ti-Sn). The effects of different electrodes on the electrochemical oxidation reactions and reaction intermediates of phenol were investigated using Uv-vis spectra. The electrogeneration of hydroxyl radicals on different electrodes was detected by the method of high performance liquid chromatograph (HPLC). The results have shown that hydroxyl radicals as electrogenerated intermediates on electrodes leads to the hydroxylation reaction of phenol. There results demonstrate that the oxidation and removal of phenol aqueous solution attributed to the further oxidation of hydroxylated products (hydroquinone and pyrocatechol).更多还原
