Abstract
Co(II) adsorption at ZnO- and ZnS-aqueous interfaces was studied with the XAFS technique. The results show the presence of both 4- and 6-coordinated oxygen-ligated Co(II) on ZnO, corresponding to Co-O distances of 1.95 and 2.1 Angstrom, respectively. At ZnS two Co-O distances are also indicated and a Co-S correlation at 2.36 Angstrom is revealed. Higher shell analysis indicates a fraction of bidentately coordinated Co(II) on ZnO. Increased coverage yields a phase structurally close to Co(OH)(2) on both adsorbents.
