Abstract

Adsorption of aliphatic amines (C<sub>1</sub>-C<sub>4</sub>) at the gold electrode was studied by tensammetry. It has been established that the experimental dependence between the gold surface coverage (Θ) and the bulk amine concentration (<i>c</i><sub>A</sub>) fits satisfactorily both by the Frumkin and Flory-Huggins isotherms. The standard Gibbs energy of adsorption, ∆<i>G</i>°<sub>ad</sub> at <i>E</i><sub>max</sub> for Θ &lt; 0.8 has been found to increase in the order methylamine &lt; ethylamine &lt; propylamine &lt; butylamine. This is rationalised in terms of surface-adsorbate, adsorbate-adsorbate and adsorbate-solvent interactions. <p>
