• Frumkin isotherm

Differential capacitance curves in the (In-Ga)/[N-methylformamide + mc KI + (1 - m)c KClO4] system are measured using an ac bridge for the following molar portions m of the surface-active anion: 0, 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, and 1. The I- anion specific adsorption in the system can be described quantitatively by the Frumkin isotherm. The principal parameters of I-anion adsorption at the (In-Ga)/N-methylformamide interface are determined by different methods.
