- Аннотация: The adsorption parameters for systems Ga/[NMF + 0.1m M KCl + 0.1(1 - m) M KClO4], Ga/[NMF + 0.1m M KBr + 0.1(1 - m) M KClO4], and Ga/[NMF + 0.1m M KI + 0.1(1 - m) M KClO4] are calculated by using the regression analysis of the adsorption potential shift vs. electrode charge dependences for the following molar fractions m of the surface-active anion: 0.05, 0.1, 0.2, 0.5, and 1 within the framework of two models. The models are based on the Frumkin isotherm with the free adsorption energy dependent on the electrode charge, of which one model takes into account the diffuse layer and the other ignores it. It is shown that for electrode charges q a parts per thousand currency sign 16 mu C/cm(2), both models provide equal accuracy; however, for higher q, preference should be given to the model that takes into account the contribution of the double layer diffuse part.
