摘要: In this account, surface tensions of mercury/ethylammonium nitrate (EAN) aqueous solutions at different compositions as a function the potential have been measured. Using first and second derivative tension curves, charge differential capacitance obtained. Assumptions based on simple hypotheses comparison EAN behavior with respect to ammonium (AN) provided information about ionic structure interface mercury/EAN solutions. The results from electrocapillarity maximum data suggest excess adsorption anions low concentrations ethylammonium cations higher concentrations. indicate that ethyl group cation would preferably be oriented towards metal mercury.
