- Аннотация: Equations for calculating the concentration of a singly charged specifically adsorbed anion, the electrode potential, the differential capacitance, and interface tension are derived under the condition that the anion transition from the outer to the inner Helmholtz plane is described by the Frumkin isotherm and the energy of this transition (ΔG A) is a quadratic function of the electrode charge q. By the example of the Hg/[H 2O + mc NH4NO3 + (1 - m)c NH4F] system, it is shown that in contrast to the linear ΔG A vs. q dependence, the quadratic dependence allows the differential capacitance curves to be adequately described throughout the m range. However, this model gives no way of describing the transition from the quadratic ΔG A vs. q dependence for small m to the linear dependence observed experimentally in binary solutions with m = 1. © 2011 Pleiades Publishing, Ltd.
