| Research Abstract |
Surface speciation of anionic species as function of environmental parameters were invesgitated by using surface complexation modeling and in-situ spectroscopic observations. This study showed that iodide adsorbs to oxide surfaces as outer-sphere complex. Iodate takes both inner- and outer-sphere complexes on oxide surfaces. Sulfate adsorbs to ferrihydrite as inner-sphere complex.
