It was pointed out earlier 1 that the structure of a zinc surface affects the adsorption of hexyl alcohol, particularly the height and width of the cathodic adsorption-desorption peaks. It was of interest to study the effect of the surface structure on the adsorption of a substance characterized by a high attraction constant in the adsorbed layer. Tetrabutylammonium iodide (TBAI) was chosen for this purpose 2.
The adsorption behavior of polycrystalline and single crystal (basal face (0001)) zinc, containing 99.999 % Zn was investigated. The face (0001) was formed by cleaving a zinc single crystal at liquid nitrogen temperature. The electrodes were electrochemically polished and prepared as already described 3. The reagents were twice recrystallized. Doubly-distilled water purified with activated carbon was used for solutions. The capacity measurements were carried out at a frequency of 65 Hz; the electrode potential was measured against SCE.
