Fig. 2From: Cesium adsorption from aqueous solutions onto Japanese oak charcoal I: effects of the presence of group 1 and 2 metal ionsIsotherms of cesium adsorption onto Japanese oak and activated charcoal from 2.50 × 10−5 mol/L CsCl2 solution (Cs+: 3.32 mg/L). The pH values of the suspension samples ranged from 9.1 to 10.2. Adsorbent: filled circles, Japanese oak charcoal: filled square, activated charcoalBack to article page
