摘要
研究了电化学条件下聚合生成的聚苯胺膜对儿茶酚及对苯二酚的催化氧化。实验分析了影响电催化的几个因素：聚合电位、膜厚、溶液酸度及底物浓度，同时分析和比较了聚苯胺膜对两种不同多酚类化合物的催化反应。提出电化学测试分析多酚类化合物的可能性。
Glassy carbon electrode modified with a polyaniline membrane was employed for the electrocatalytic oxidation of catechol and p-dihydroxybenzene.Several factors affecting the electrocatalytic oxidation have been investigated,such as the polymerization potential,film thickness,solution acidity,and substrate concentrations.The catalytic reactions of the two substrates were compared.The possibility of using this electrochemical reaction for polyphenolic compound analysis is proposed.
