Adsorption of Sodium Humate, Cordanum, and Verapamil on a Mercury Film Electrode: A Study by the Integration of Capacitive Currents

Method of integrating capacitive currents is used for the first time to examine adsorption of sodium humate, cordanum, and verapamil on a mercury film electrode. Values of the limiting adsorption, adsorption equilibrium constants, and free energy of the adsorption process are obtained.
