Adsorption behavior of radioactive cesium by non-mica minerals

Figures & data

Figure 1 The distribution coefficients (K _d) of Cs by minerals and clay minerals at different Cs concentrations. Deviation of duplicate measurement was within the symbols

Figure 2 Fractions of Cs at 2 × 10⁻⁹ mole L⁻¹ desorbed by different univalent cations at 20°C from montmorillonite, illite, kaolinite, MnO₂, mordenite, halloysite, and sericite. Deviation of duplicate measurement was within the symbols

Figure 3 The sequential desorption of the adsorbed Cs at 10⁻⁹ mole L⁻¹ (a), 10⁻⁵ mole L⁻¹ (b), and 10⁻⁴ mole L⁻¹ (c) by the 0.1 M LiCl solution, the 1 M KCl solution, the 1 M HCl solution, and the residual from montmorillonite, illite, kaolinite, MnO₂, mordenite, sericite, and halloysite. Desorption data of Cs at 10⁻⁵ mole L⁻¹ from halloysite was not measured because of the lack of the sample of halloysite
