Abstract

Numerical calculations are carried out for potential dependences of the surface coverage and the electrode differential capacitance in the case of co-adsorption of two organic substances with different orientation of their dipole molecules in the adsorption layer. It is shown that at strong attraction of two different adsorbed molecules these dependences can be adequately described by the model of two parallel capacitors combined with simple Frumkin isotherm. The obtained results allow revisiting data on the individual adsorption of simple aliphatic molecules at ideally polarizable electrode.
