Adsorption of methylamines and pyridme homologues on platinum electrodes in alkaline aqueous solutions was investigated by means of periodic triangular wave voltammetry and impedance measurements. The orders of the adsorptive effects are methylamine > dimethylamine > trimethylamine, and y-picoline

✦ Synopsis
The adsorption processes occuring on the platinum electrode (taken as an example of a transition metal displaying strong electrocatalytical properties) have been classified into three groups: (I) The surface complexing processes with the participation of the adsorbate n-electrons and the hybrid dorbitals of the metal, (2) the adsorption in the second ad-layer of the Pt interracial region, and (3) the electrochc'mical reactions of the organic molecules with the water molecules chemisorbed on the platinum electrode,
The nature of the binding forces opcrating within each group has been qualitatively described.
