Radiotracer study of the specific adsorption of anions on oxides

摘要

The possibility of the extension of the radiotracer technique to the study of specific adsorption of anions on oxides is discussed. It is shown that the indirect version of the so-called "thin foil" method could be a useful tool for the clarification of adsorption behavior of certain species. The main tendencies characterizing the adsorption of phosphate species on hematite and γ-Al_2O_3 are demonstrated using ~(35)S-labeled sulfate ions as indicator species.
