Abstract
Based on a review of recent experimental data on heavy metal sorption on clay minerals (montmorillonite, illite, and kaolinite), a method was developed to estimate the unified characteristics of the density of surface sorption sites and constants of reactions occurring on them, such as Meaq ⇄ Mesurf. A model combining the description of ion exchange sorption in the presence of Na electrolytes and pH-dependent chemical adsorption on the amphoteric sites of the edge faces of the three mentioned phases provided a satisfactory approximation of experimental data of various authors and an approach to the understanding of the essence of differences in the properties of sorbents and behavior of metal cations. It was supposed that this approach is helpful as a reconnaissance stage during the analysis of other more complex systems (multicomponent solutions, polymineralic soils, etc.).
