Keywords:Cesium desorption, Hydrothermal treatment, Volume reduction, Ion exchange, Decontamination

Multivalent cations (M2+/M3+) was successfully used in present study to desorb Cs from both its saturated vermiculized biotite to clarify the mechanism of Cs removal process on microscale and actual soil for the demonstration of Cs removal from radioactive materials.
