Special electrocapillary drop-time measurements, voltammetry of surfactants on renewed miniaturized stationary mercury electrodes, principles of the contractive and contractive & expansive measuring systems and three contributions to the theory of adsorption processes (adsorption isotherms, the peak potential shifts with concentration and the relative adsorptivity of surfactants) are discussed.p. 235-241enopen accessArticle47333-3
