摘要 实验采用自组装膜法将巯基三唑修饰在金电极上.结果表明:修饰后的金电极对对苯二酚产生明显的催化作用;扫描速率的平方根与对苯二酚氧化峰电流存在相关关系,表明对苯二酚的氧化还原反应受扩散控制;对苯二酚浓度与其氧化峰电流呈较好的线性关系,可以用来分析和检测该浓度范围内对苯二酚的含量. Using the gold electrode self-modified by Mercapto-triazole, the experiment produces the result that shows that the gold electrode modified by mercapto-triazole has significant catalysis on the Hydroquinone; there is a correlation between the square root of scan rate and the current of oxidation peak of Hydroquinone, which indicates that the redox reaction is a process controlled by expanding. A good correlation also exists between the concentration of Hydroquinone and its current of oxidation peak, which could be used to analyse and test the concentration of hydroquinone.
