摘要
电化学阻抗谱(EIS)是表征电化学体系特征及其过程机理的重要技术,但解谱模型不一致限制了其应用.为此,采用CR传输线模型中的8CRR等效电路拟合文献报道的杯[4,8,12]芳烃离子选择电极与Na+、Ca2+及Fe3+作用的EIS;并根据电荷转移电阻、表面吸附、扩散阻力和空间电荷层电容等不同特征,揭示了作用机理的共性与差异.结果表明,所采用的方法可操作性强,结果客观,具有一定的理论和应用价值.
With a view to the restriction of electrochemical impedance spectroscopy（EIS） in describing many types of electrochemical systems and revealing their electrode process mechanism and kinetics related to inconsistent models,we have adopted CR transmission line model（CRM） to reanalyze and fit the EIS data for interactions of p-tert-butylcalixarene functionalized gold electrode with Na＋,Ca2＋ and Fe3＋ reported in literatures.The similarity and difference in the action mechanisms have been revealed in relation to charge transfer resistance,surface adsorption,diffusion resistance and space charge layer capacitance.It has been found that the established method is practicable and reliable,showing significance in both theory and application.
