Adsorption Kinetics and Electrode Processes

Journal of the American Chemical Society, 1957
Prof. H. A. Laitinen (Urbana): We have used double layer capacity measurements to measure adsorption as a function of time during the life of slowly forming mercury drops. For many substances that are not extremely surface active, so that the solution concentration is 1 to 10 mM, the double layer capacity per unit area is essentially constant during
