【摘要】 用薄层光谱电化学技术研究了阳离子艳蓝的电还原过程。薄层循环伏安图表明阳离子艳蓝有一对接近可逆的氧化还原峰。从光谱发现它有顺反异构体互变现象与变色效应。在氧存在时，循环伏安图和光谱图上均出现新峰，推测阳离子艳蓝分子与氧分子能形成电荷转移络合物．测得阳离子艳蓝电还原的式电极电势、电子转移数以及扩散系数等参数。并讨论了可能的电极过程。更多还原

【Abstract】 The electrochemical reduction of Basic Blue was investigated by means of thin-layer spectroelectrochemical technique at SnO₂ film optically transparent electrode. The nearly reversible redox peaks of basic blue were shown on the thin layer cyclic voltammogram.Spectroscopic experiment found the cis-trans-tautomerism and the color change effect of basic blue. In the presence of Oxygen, a new peak appears on the cyclic voltammogram and on the spectrum.It was supposed that the basic blue and the oxygen molecule can form a charge transfer complex. The formal potentials and the electron transfer numbers as well as the diffusion coefficient of basic blue were determined by means of thin-layer spectroelectrochemical technique.The possible electrode process was discussed on the basis of these measurements.更多还原
