Abstract
The adsorption of H+, OH− and ARS (Alizarin Red S) onto hydrous fluorapatite surfaces and Ca2+—ARS complexation in solution were studied by means of combined potentiometric and spectrophotometric titrations, as well as zeta potential and FT-IR measurements. Corresponding equilibrium constants of surface and solution reactions are determined. The application in flotation processes is discussed.
