| 摘 要： | 研究了２，６－吡啶二甲酸在玻璃电极上的电化学聚合物薄膜修饰电极的电化学特性，发现其对儿茶酚和对苯二酚析电化学氧化具有显著的催化作用，使它们的氧化电位降低，峰电流显著增大。从聚合物膜与多酚化合物的氢键作用对催化机理进行了探讨。该聚合物膜修饰电极可用于多酚的电化学测定。

| Abstract: | The polymerization conditions of 2,6 pyridnedicarboxylic acid at glassy carbon electrode and its electrochemical characteristics have been investigated.It is found that in the polymer ization strong catalytic effect towards the electrochemical oxidation of catechol and hydroquinone is affected.It is believed that the hydrogen bonding between the polymer and the polyphenolic compounds are responsible for the catalytic effect.The modified electrode can be applied to the electrochemical determination of catechol and hydroquinone. |
