Abstract
The development and refinement of a two-phase model for describing the potentionmetric properties of crosslinked weak acid polyelectrolyte gels and their linear analogues are discussed. Application of this approach has been facilitated by identifying functional group heterogeneity and separate phase effects as the major complications in the description of ion binding by humic substances. By their separation and quantification, equilibrium properties of these systems have been anticipated. This approach may be described as a "discrete ligand" model with solution chemistry effects taken into consideration. Examples of its applications are enumerated and an attempt is made to compare the approach with others.
