Abstract
ADSORPTION of phosphate on hydrous metal oxides is of considerable importance in soil fertility and eutrophication studies. Phosphate is known to be adsorbed on the hydrous oxides displacing aquo (M–OH2) and hydroxo (M–OH) ligands; its adsorption makes the oxide surface less positive1–3. I report here on a quantitative study in which phosphate was adsorbed on to hydrous oxides, displacing the ligands, and the simultaneous change in the net surface charge was measured.
