摘要: In this paper a quantitative analysis of the coadsorption ratio for oxides, r OH , that is number − ions coadsorbing with each specifically adsorbing metal ion at given pH, given. This an important double-layer parameter. It shown because high accumulation charge on surface and effective compensation by countercharge in Stern plane, can be established satisfactory precision using Gouy-Stern theory only. Computed values depend primarily distance between pH pzc to lesser extent indifferent electrolyte concentration. If layer capacitance high, it not critical Agreement data literature new measurements Cd 2+ adsorption rutile hematite satisfactory.
