研制了聚毗咯／ＮＱＳ修饰金带电极，讨论了ＮＱＳ／ＰＰｙ的电聚合过程及实验条件对金电极上吡咯聚合物膜性质的影响；用成核及生长理论解释了阴离子ＮＱＳ对电聚合过程计时电流曲线的影响，优化了ＮＱＳ／ＰＰｙ／Ａｕ电极的制备条件．该修饰电极稳定性好，对辅酶Ⅰ在金电极上的还原有催化作用．在ｐＨ＝７．０时催化电流在４．０×１０￣（－５）～１．５×１０￣（－３）ｍｏｌ／Ｌ范围内与ＮＡＤ￣＋ 浓度有线性关系，探讨了电催化作用的机制．
The polyglutamine / NQS modified gold banding electrodes were developed. The effects of NQS / PPy electropolymerization process and the experimental conditions on the properties of the pyrrole polymer films on the gold electrode were discussed. The nucleation and growth theory was used to explain the effect of anionic NQS on the electropolymerization Chronoamperometry curve, the preparation conditions of NQS / PPy / Au electrode were optimized. The modified electrode has good stability and catalyzes the reduction of coenzyme I on the gold electrode. The linear relationship between the catalytic current and NAD + concentration in the range of 4.0 × 10 -5 to 1.5 × 10 -3 mol / L at pH = 7.0 was discussed. The electrocatalysis Mechanisms.
