【摘要】 采用滴涂法和恒电位沉积法制备了聚纳米金/乙炔黑复合膜修饰玻碳电极。运用循环伏安法对对苯二酚在该修饰电极上的电化学行为进行了研究,实验结果表明,该复合膜修饰玻碳电极对对苯二酚具有良好的电催化性能。利用差分脉冲伏安法进行测定时发现,在1.0×10-7~2.0×10-4 mol/L浓度范围内,对苯二酚的浓度与氧化峰电流有良好的线性关系,相关系数为0.998;在有50?mol/L邻苯二酚存在的情况下,对苯二酚的浓度与氧化峰电流在5.0×10-6~2.0×10-4 mol/L浓度范围内有良好的线性关系,相关系数为0.992。另外,当信噪比为3时,对苯二酚的检出限为5.0×10-8 mol/L。更多还原

【Abstract】 The polymer nano Au / acetylene black composite film modified glassy carbon electrode was prepared with the drop coating method and potentiostatic deposition metohd. The electrochemical behaviors of hydroquinone on the modified electrode were studied by cyclic voltammetry. The results showed that polymer nano Au/acetylene black composite film modified glassy carbon electrode had excellent electrocatalytic performance on hydroquinone.更多还原
