摘要 在中性溶液中用重复电位扫描法在玻碳电极上制备了亚甲基兰混合中性红聚合膜。其聚合是在高电位引发下,氧化中性红和亚甲基兰产生自由基发生链式引发聚合时该聚合物修饰电极在pH值为8.4时对多巴胺有良好的催化氧化能力,在3×10^-6~3×10^-4mol/L范围与峰电流成线性关系。可用于多巴胺的测定。 The formation of a radical cation, by electrochemical oxidation of the methylene blue and neutral red dye in neutral aqueous solution, is controlled by diffusion towards the glassy carbon electrode surface. The modified electrode was an effective mediator for the electrocatalytic oxidation of the dopamine and the modification allowed dopamine to be determined in the range of 3×10^-6~3×10^-4mol/L in pH 8.4 tris -HCI buffer solution.
