摘要
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．
In this paper, the polymerization conditions and polymerization mechanism of 2, 6-pridinedicarboxylic acid at grassy carbon electrode are investigated. The experiment results show that the polymer can catalyze the electrooxiation of dopamine. The oxidation peak potential shifts negatively about 230 mV,and there is a large increase in oxidation current. The catalytic currents increase linearly with the concentration of dopamine in the range of 1.0 ×10-6~1.0 ×10-2mol/L. The modified electrode has been applied to the determination of dopamine in drug with satisfactory results.
