Reversibility and modeling of adsorption behavior of cesium ions on colloidal montmorillonite particles

Iijima, Kazuki ; Tomura, Tsutomu*; Shoji, Yoshiyuki*

Sorption and desorption behavior of Cs onto montmorillonite colloids was investigated. The ion exchange and surface complexation model can successfully reproduce the sorption and desorption behavior of Cs. Conditioning montmorillonite in higher Cs concentration than 0.005M causes decrease of interlayer distance which may lead to fixation of Cs in the interlayer. Sorption reversibility of Cs on montmorillonite colloids can be expected in this study due to lower Cs concentration than 0.0001M.
