摘要
应用循环伏安法测试了1mol·L-1硫酸水溶液和含苯酚的1molL-1硫酸水溶液体系的电化学行为,分析电极过程中苯酚及其中间产物在电极表面的吸附特征以及苯酚氧化的可逆性及其反应步骤;提出了特性吸附电位Ead;当电极电位大于Ead时,不同的氧化产物开始生成.
The electrochemical behaviors of platinum electrode were studied by cyclic voltammetry in 1mol/L sulfuric acid solution and 1mol/L sulfuric acid solution contained phenol. The adsorption characteristics of phenol and the intermediat on electrode surface have been discussed. The reactive reversibility and oxidation mechanism of phenol on electrode process have been investigated.The potential of characteristic adsorption was suggested. The various products woud be formed when the electrode potential was greater than the one of characteristic adsorption.
