Abstract : Frumkin-isotherm parameters are reported for 1-butanol, 1-pentanol, and cyclohexanol, in solutions containing 0.05, 0.1, or 1 M concentrations of KF, KCl, NaClO4, or Na2SO4, over a range of potentials. The nature and concentration of the electrolyte, as well as the potential, influence the magnitudes of the interaction parameter and of the adsorption coefficient. These effects are in qualitative accord with known facts about the adsorbabilities of the alcohols and electrolytes. The Frumkin isotherm describes the data well, except in the presence of fairly strongly specifically adsorbed anions. (Author)
