Abstract

Abstract: 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.
