Electrode double layer measurements and voltammetry of some organosulfur compounds in sulfolane

Creator:: Starkovich, John A.
Abstract:: A new pulse method for measuring differential double layer capacitances has been developed in this work. The technique is based on the determination of the cell time constant which, for an ideally polarized test electrode-solution interface, is composed of the double layer capacitance and solution resistance. By applying small step...

Stationary electrode voltammetry and chronoamperometry in an alkali metal carbonate-borate melt

Creator:: Petcoff, Darrell George
Abstract:: The electrochemistry of the lithium-potassium-sodium carbonate-borate melt was explored by voltammetry and chrono-amperometry. In support of this, a controlled-potential polarograph and associated hardware was constructed. Several different types of reference electrodes were tried before choosing a porcelain membrane electrode containing a silver wire immersed in a silver sulfate melt. The...
