研究了2，6－吡啶二甲酸在玻碳电极上电聚合的实验条件及其聚合机理，发现该修饰电极对神经递质多巴胺的电氧化有显著的催化作用，使氧化电位降低230mV，峰电流大大增加．多巴胺浓度在1．0×10－6～1．0×10－2mol／L范围内与氧化电流有良好的线性关系．该修饰电极应用于多巴胺注射液的分析，获得满意的结果．
The experimental conditions and polymerization mechanism of 2,6-pyridinedicarboxylic acid on the glassy carbon electrode were investigated. The results showed that the modified electrode catalyzed the electroporation of neurotransmitter dopamine significantly and the oxidation potential was reduced by 230mV. The peak current greatly increase. Dopamine concentration in the range of 1.0 × 10-6 ~ 1.0 × 10-2mol / L and the oxidation current has a good linear relationship. The modified electrode was applied to the analysis of dopamine injection, to obtain satisfactory results.
