Previous workers concluded that cadmium ions adsorb onto the goethite surface by the formation of bidentate surface complexes.11,12 However, the cadmium adsorption data and our calculations (see Figure 3) shows that cadmium adsorbs on goethite mainly on one surface hydroxyl group, forming monodentate complexes, according the following reaction ... [Pg.386]

The adsorption affinity of Cd ions on the adsorbents following the order titania > goethite > silica. The adsorption of Cd(II) ions was also investigated for three selected cadmium concentrations 1 x 10 6, 1 x 10 4 and 1 x 10 3 M, and the same sequence was observed. [Pg.386]
