Abstract
Effect of a condensed layer (CL) of 1-adamantanol (1-AdOH) during individual adsorption and coadsorption with tetraalkyl cations on the kinetics of the electroreduction (ER) of cation Ag+ at a mercury electrode is studied with the aim of revealing the link between the rate of electrode processes and the structure of two-dimensional CL. It is shown that ER of Ag+ occurs by means of penetration of the depolarizer particles through the adsorption layer. Polarization curves are calculated under the assumption that the potential barrier for ER of Ag+ in the presence of CL of 1-AdOH is defined by the work for overcoming two-dimensional pressure in the layer. Satisfactory agreement between experimental and calculated dependences in the region of ascending branches of polarization curves is demonstrated. It is established that the degree of the inhibiting action of mixed adsorption layers (as compared with individual CL of 1-AdOH) on ER of Ag+ depends on the 1-AdOH activity in solution and the nature of the organic cation. It is assumed that the latter effect is caused by the surface activity of cations studied.
