Abstract

Cesium ions (Cs⁺) strongly adsorbed in vermiculite clay (Verm) were efficiently desorbed by reacting with magnesium ions (Mg²⁺). 70–90% removal of adsorbed Cs⁺ ions was achieved when Verm loaded with 0.1–100 µmol g⁻¹ Cs⁺ (corresponding to 0.016–16% of the saturation amount) was mixed with 3.0 mol L⁻¹ aqueous Mg(NO₃)₂. X-ray analyses and powder X-ray diffraction measurements on solid samples confirmed that ion exchange occurred between Cs⁺ ions in the interlayer space and Mg²⁺ ions.
