Analytical theoretical solutions are deduced for the current-potential response, concentration profiles and interfacial potentials of electron-coupled ion transfers in the cyclic voltammetry with thick film-modified electrodes. The theory covers a wide variety of possible situations, namely, the redox transducer can be either immobilized on the working electrode or freely diffusing in the organic film, and the ion transfer can be either simple or complicated by homogeneous chemical processes. A comparative and comprehensive study of each case is performed, establishing the key parameters that define the behaviour of the system, as well as guidelines to analyse its electrochemical signal.

在厚膜改性电极上使用固定与可溶性氧化还原换能器对电子耦合离子转移进行分析建模

推导出具有厚膜修饰电极的循环伏安法中电子耦合离子转移的电流-电位响应、浓度分布和界面电位的分析理论解决方案。该理论涵盖了多种可能的情况，即氧化还原换能器可以固定在工作电极上，也可以在有机膜中自由扩散，离子转移可以通过均相化学过程进行简单或复杂。对每个案例进行比较和全面的研究，建立定义系统行为的关键参数，以及分析其电化学信号的指南。
