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。
Poly (toluidine blue) / carbon nanotubes / glassy carbon electrodes were prepared by electropolymerization of toluidine blue on multiwalled carbon nanotubes modified glassy carbon electrode. The electrochemical behavior of three hydroquinone isomers on the electrode was studied . The results showed that the oxidation of hydroquinone isomers on the modified electrode showed excellent electrocatalytic performance and selectivity. Inspected a variety of influencing factors. In the range of 5.0 × 10-6 ~ 2.0 × 10-4mol / L, the anodic peak current of the dihydroxybenzene isomers has a linear relationship with its concentration, and a simultaneous voltammetric analysis of three kinds of dihydroxybenzene isomers The new method
