Аннотация:It is established that the characteristic parameters for the generalized surface-layer (GSL) model n and k determine the form of the dependence of the integral capacitances of the entire compact layer K//0//2 and of the space between the inner and outer Helmholtz planes K//1//2 on the coverage theta . Plots of the dependence of the coverage, the electrode charge, the value of q plus q//1, and the differential capacitance on the potential have been calculated for the case of the adsorption of tetrabutylammonium cations with the use of the equation of the GSL model. The results are compared with a calculation based on the Alekseev-Popov-Kolotyrkin model.
