The CD-MUSIC model is able to successfully predict phosphate speciation on ferrihydrite nanoparticles under a wide range of conditions, pointing out that the dominant species are the bidentate surface complexes. Ferrihydrite nanoparticles may dominate the ion binding properties of the natural oxide...
