摘要

Not all electrochemists realize what contribution to electrochemistry resulted from the introduction in 1922 of the dropping mercury electrode (DME) to electrolysis. It is still the only electrode with a well defined, freshly renewable surface. It is also an electrode for which we know the exact time of its first contact with the solution, which can be helpful in investigation of kinetics of adsorption. Perhaps the most important innovation was the use of controlled potential in an era when applied current electrolysis predominated. Using dropping mercury electrodes, the first reproducible current voltage (i-E) curves were recorded and, soon, the importance of the limiting current and its advantages over Tafel plots were recognized. From a practical point of view, the understanding of the role of oxygen and the importance of its removal in investigations of reduction processes became clear. Investigation of polarographic i-E curves enabled the roles of various types of transport to the electrode (such as migration, diffusion, and convection) and chemical reactions to be distinguished, as well as the various functions of the supporting electrolyte to be identified.
