Abstract

The surface charges on hematite, kaolinite and on kaolinite coated with hematite (kaolinite-hematite system) were measured and successfully described using the model (Four-Layer Model) developed by Bowden and co-workers (1977; 1980a; 1980b). The surface charge was also calculated theoretically, according to a computer program developed by Barrow (1987). Significant differences were pointed out for the surface properties of the three solids examined. Anion-specific adsorption was observed for hematite and kaolinite-hematite, and cation adsorption for kaolinite.
