Abstract : The electrochemistry of various dissolved gases has been investigated as a function of the gas, solution pH, supporting electrolyte, electrode material, and the preconditioning of the electrode surfaces. These investigations have been conducted through the use of voltammetry, chronopotentiometry, and galvanostatic measurements. The gases investigated include oxygen, hydrogen, sulfur dioxide, hydrogen cyanide, carbon monoxide, and carbon dioxide. Electrodes have been constructed from a number of materials including platinum, gold, silver, nickel, palladium, iridium, rhodium, and mercury. As a result of the investigations kinetic parameters for several electrochemical reactions of dissolved gases have been measured. Also for several of the investigations mechanisms that are consistent with the experimental data have been postulated for the electrode processes involving dissolved gases. A numer of analytical procedures for various dissolved gases have resulted from the work under the subject contract and the under the subject contract and the understanding of the effect of electrode material on the rate of several gases has been improved.(Author)
