Аннотация:The data on coadsorption of tetraethylammonium (Et4N+), tetrapropylammonium (Pr4N+), and tetrabutylammonium (Bu4N+) cations with Cl-, Br-, and I- anions on an uncharged mercury electrode are compared with the models of coadsorption in a common monolayer and two parallel layers. The second model is shown to be in best agreement with experimental isotherms. However, the least discrepancy between calculations and experimental results is obtained when coadsorption of mentioned cations and anions is described by the Frumkin isotherm for neutral molecules with certain effective adsorption parameters.
