Adsorption at the Polarized Mercury/Tetrahydrofurfuryl Alcohol Interphase
quote

Electrocapillary studies of tetrahydrofurfuryl alcohol (THFA) in aqueous specifically and non-specifically adsorbed base electrolytes were carried out. The primary results will be compared with those using a Kowalski impedance bridge method. Derived results comprising of standard electro-chemical free energies of adsorption, isotherms, surface excesses and other parameters will be presented to demonstrate unusual distinctive two-point orientation effects not hitherto reported in the literature for saturated heterocyclic compounds. Calculations of the fraction of adsorbed THFA in varying positions on the Hg surface as a function of changing bulk concentrations at constant potential will be discussed.
