Response Mechanism of Polymeric Liquid Junction-Free Reference Electrodes Based on Organic Electrolytes.

ABSTRACT: To achieve a transition from conventional liquid-junction reference electrodes (LJF REs) to their all-solid-state alternatives, organic electrolytes are often introduced into the polymeric electrode membranes. In this article, we implement a theoretical approach to the explanation and quantification of the boundary potential stabilization phenomenon for the electrodes modified with organic electrolytes (Q⁺B^-). For the first time, stabilization of the phase boundary potential due to the partition of lipophilic ions of the Q⁺B^- electrolyte between the polymeric and aqueous phases is numerically simulated to predict the LJF electrodes behavior. The impact of the hydrophilic electrolyte on the potential stabilization is demonstrated both numerically
