Applicationsof Potentiometric Sensors in Nonaqueous Solutions

Current trends in electrochemical studies of nonaqueous solutions are discussed with the emphasis on experimental approaches judged to be particularly promising for the future development of both fundamental and applied aspects of the field of solution chemistry. Topics include recent developments in the application of potentio— metric sensors to nonaqueous solutions, the potentialities of such new materials as reactively sputtered iridium oxide as hydrogen ion sensors, and the demonstrated or potential advantages of micro— electrodes with diameters less than approximately 20 urn in cyclic voltamnetry and a variety of other electrochenical techniques applicable to nonaqueous solutions. The extension of electrochemical measurements to nonpolar media is emphasized. Recent developments in certain other areas such as applications of solid electrolytes and chemically modified electrodes, and studies of interfaces between immiscible solvents, are briefly discussed.
