Fig. 5From: Cesium adsorption from aqueous solutions onto Japanese oak charcoal I: effects of the presence of group 1 and 2 metal ionsFreundlich plots for 2.50 × 10−5 mol/L CsCl2 solution including LiCl (a), NaCl (b), and KCl (c). The pH ranges of the suspension samples shown in (a), (b) and (c) were 8.9–10.1, 7.8–10.2 and 8.7–10.1, respectively. Molar concentrations of metal chloride added to the cesium chloride solution: filled diagonal, no addition; filled square, 5.1 × 10−3 mol/L; filled triangle, 5.1 × 10−2 mol/L; filled circles, 5.1 × 10−1 mol/LBack to article page
