The recently proposed interface equilibria‐triggered dynamic diffusion model of the boundary potential has proven its high predictive efficiency for quantification of the ion exchange and co‐extraction effects at the interface, as well as of the trans‐membrane transfer effect, on the electrode response. It is applicable for both ion exchanger‐based and neutral carrier‐based electrodes. In this communication, the adaptability of this model to more complex cases, when non‐ion‐exchange extraction processes at the interface (partition of organic acids’ and bases’ molecular forms and extraction of ionic associates) are coupled with protolytic equilibria in the aqueous phase and with self‐solvation process in the membrane phase, is demonstrated. By the example of electrodes reversible to ions of highly lipophilic physiologically active bases and acids (amiodarone, verapamil, vinpocetine, salicylic acid), it is shown that the peculiarities of their functioning, such as a very strong pH effect on the potential of cation‐selective electrodes, non‐monotonic pH dependence of the potential and super‐Nernstian response slope in certain pH region for a salicylate‐selective electrode, are well described within the model.

接口平衡触发模型中非离子交换萃取和膜内相互作用对离子选择电极响应的影响的描述

最近提出的界面势的界面平衡触发的动态扩散模型已证明其具有很高的预测效率，可量化界面处的离子交换和共萃取效应以及跨膜转移效应对电极响应的影响。它适用于基于离子交换剂的电极和基于中性载体的电极。在这种交流中，当界面上的非离子交换萃取过程（有机酸和碱的分子形式的分配以及离子缔合体的萃取）与水溶液中的蛋白水解平衡相结合时，该模型对更复杂情况的适应性证明了在膜相中具有自溶过程。
