摘　　要：利用电化学还原的方法制备了4-氨基吡啶共价修饰玻碳电极,通过循环伏安法研究了对苯二酚和邻苯二酚在此修饰电极上的电化学行为.结果表明,4-氨基吡啶修饰电极对对苯二酚和邻苯二酚有较好的电催化活性和电分离作用.利用微分脉冲伏安法,用4-氨基吡啶修饰电极可同时及定量检测对苯二酚和邻苯二酚,在2.5×10^(-6)~1.1×10^(-4)mol/L范围内,二者的微分脉冲伏安响应与浓度呈良好的线性关系.A glassy carbon electrode（GCE） was covalently modified by 4-Aminopyridine via an electrochemical redution process. The electrochemical behaviors of hydroquinone and catechol on the modified electrode were studied by cyclic voltammetry. 4-Aminopyridine modified electrode exhibited an excellent electrocatalytic ability and electro-separation. Differential pulse voltammetry（DPV） was used in the simultaneous and quantitative determination of hydroquinone and catechol. The DPV response of two compounds increased linearly with the concentration in the range of 2.5×10（-6）-1.1×10（-4） mol/L.
