摘　　要：利用循环伏安法研究了聚合电位和聚合电量对茜素红 S掺杂聚吡咯薄膜修饰玻碳电极性质的影响 ,考察了不同电位范围内修饰电极的电化学特性 .发现在茜素红 S的氧化还原过程中存在着茜素红 S分子与聚吡咯链的相互作用 ,且这一相互作用敏感于扫描正电位限 .基于实验结果 ,提出了可能的茜素红The cyclic voltammetry was employed to study the influence of the polymerization potential and charge on the property of the polypyrrole(PPy) film electrode containing Alizarin Red S(ARS), and of the scan potential range on the redox behavior of ARS. It has been demonstrated that the interaction of ARS molecules with PPy chains exists in the redox process of ARS between -0 60 V and 0 40 V. Based on the experimental finding, a possible reaction mechanism was suggested.
