Keywords:Cesium desorption, hydrothermal , volume reduction, ion exchange

Cesium ions (Cs⁺) strongly intercalated in vermiculite clay (Verm) had been effectively removed using sea water for its free utility, totally environmental friendly feature and within containing numerous salt by hydrothermal treatment process (HTT) which can help significantly promote desorption by cation exchange mechanism in subcritical condition.
