Aqueous Co(II) sorption onto alpha-Al2O3 at pH 8.1 and surface concentrations (Gamma) of 0.16 to 11.3 mu mol m(-2) has been studied by XAFS spectroscopy. At low Gamma, Co adsorbs in a monodentate fashion or in a bridging bidentate fashion and is present as small oligomers. A Co(OH)(2)-like phase forms at high Gamma.
