| 摘要: 用薄层池原位紫外光谱电化学法研究了辅酶Ⅰ(NAD)在银电极上的电化学配位反应机理。实验结果表明：NAD能与溶出的银离子生成配合物，该配合物的配位反应是一种可逆过程，用光谱电化学的Nernst图解分析获得银离子与NAD配合物的主要存在形式是［Ag(NAD)2］+，银离子是与NAD分子的腺嘌呤基团形成配合物的。配合物的银离子与银电极表面发生异相电子交换反应，该电化学反应是受吸附控制的准可逆电极过程。 |

| Abstract: The electrochemical coordinate reaction mechanism of nicotinamide adenine dinucleotide (NAD) on silver electrode has been studied by in situ ultra-violet spectroelectrochemistry. The results of experiment showed that NAD could formed coordination compound with silver ion which came from the electrolysis oxidation of silver electrode. The coordination reaction was a reversible process. The coordination ratio of silver ion with NAD was analyzed by spectroelectrochemical Nernst figures. The main complex of siver ion with NAD was ［Ag(NAD)2］+. The coordination reaction formed by silver ion with adenine function of NAD. The electrochemical reaction mechanism of the complex on silver electrode was discussed. It is clear that the electrochemical reaction of the complex is a quasi-reversible and adsorptive process, The heterogeneous electron exchange reaction happened on the surface of silver electrode with nicotinamide function of NAD. |
