Modulation of Reactions on Bipolar Electrodes Using Ion-Selective Membranes

摘要

Bipolar electrochemistry uses isolated electrodes immersed in a solution. Unlike ordinary electroanalysis using the three-electrode system, an electrical field is intentionally generated in the electrolyte solution employing the Ohmic drop to generate interfacial potential differences at the anodic and cathodic poles. Electrochemiluminescence (ECL) is coupled with the reaction to be detected to obtain the information about redox reactions. A problem with this method is that the electrodes are electrically floating and the interfacial potential difference cannot be controlled intentionally. To solve this problem, we used an ion-selective membrane (ISM) formed on one part of each electrode.
