Evidence for Surface Precipitation of Phosphate on Goethite

Evidence for Surface Precipitation of Phosphate on Goethite

Recent studies have suggested that the interaction between phosphate and goethite includes ternary adsorption/surface precipitation as well as surface complex formation. The ternary adsorption/surface precipitation process envisioned involves the dissolution of the goethite crystal and subsequent adsorption of iron on the surfacebound phosphate.
