✦ Synopsis

The adsorption of normal aliphatic alcohols on a polarized Hg electrode from solutions in ethylene glycol has been investigated by capacity measurements. The experimental data have been processed in terms of the Frumkin-Damaskin theory. Results have shown that the adsorption of alcohols (from hexanol to undecanol) conforms well to a Frumkin isotherm with particle-particle interaction corresponding to attraction. The derived parameters have been compared to those for adsorption from aqueous solutions and a structural picture of the adsorption layer has been outlined.
