Аннотация:By the regression analysis of dependences of the adsorption potential shift (E (ads)) on the electrode charge in systems (Tl-Ga)/[NMF + 0.1m M KI + 0.1(1 - m) M KClO4], (Tl-Ga)/[NMF + 0.1m M KBr + 0.1(1 - m) M KClO4], and (Tl-Ga)/[NMF + 0.1m M KCl + 0.1(1 - m) M KClO4] with the following m fractions of the surface-active anion: 0.05, 0.1, 0.2, 0.5, and 1, the adsorption parameters are calculated in terms of two models based on the Frumkin isotherm both considering the free adsorption energy as a quadratic function of the electrode charge, where one model takes into account the diffuse layer and the other ignores it. It is shown that for the studied electrode charges q a parts per thousand currency sign 2 mu C/cm(2), both models provide equal accuracy in calculating E (ads) in the systems under study.
