New concept of a reference electrode for electrochemical systems resolves a problem of a poor
potential stability of refence electrodes based on the distribution of a strongly
hydrophobic common cation between two immiscible electrolyte solutions (TTTES). The use of a
polarizable metal electrode instead of a classical reference electrode is demonstrated in
a modified conventional four-electrode cell with TTTES. A simple battery operated potentiostat
controls the working electrode potential in a three-electrode configuration. The working metal
electrode then serves as a polarizable reference organic solvent electrode in a four-electrode
system for the polarization of the water/organic solvent interface.
