摘　　要：通过电聚合甲苯胺蓝于多壁碳纳米管修饰玻碳电极上制备了聚甲苯胺蓝/碳纳米管/玻碳电极,研究了三种苯二酚异构体在该电极上的电化学行为。结果表明,修饰电极对苯二酚异构体的氧化表现出优异的电催化性能和选择性。考察了各种影响因素。在5.0×10-6～2.0×10-4mol/L的范围内,苯二酚异构体的阳极峰电流与其浓度有线性关系,建立了一种同时伏安分析3种苯二酚异构体的新方法。The pTB/MWNTs/GC electrode was fabricated by electropolymerization of toluidine blue at a multi-walled carbon nanotubes modified glassy carbon electrode.The electrochemical performance of dihydroxybenzene at the modified electrode has been investigated by cyclic voltammetry.It is found that the pTB/MWNTs/GC electrode showed excellent electrocatalysis and selectivity for the oxidation of dihydroxybenzene.A linear relationship between peak current and the concentrations of hydroquinone,catechol and resorcinol...
