Dissolution behavior of 137Cs absorbed on the green tea leaves

The green tea leaf was dipped in the 137 CsCl solution to elucidate the dissolution behavior of 137 Cs. The IP observation showed that 137 Cs was not uniformly adsorbed on the tea leaf, even if the tea leaf was dipped in the homogeneous solution. The activation energy of 137 Cs dissolution was estim...

Description
Summary:The green tea leaf was dipped in the 137 CsCl solution to elucidate the dissolution behavior of 137 Cs. The IP observation showed that 137 Cs was not uniformly adsorbed on the tea leaf, even if the tea leaf was dipped in the homogeneous solution. The activation energy of 137 Cs dissolution was estimated to be 0.045 eV, indicating that most of 137 Cs would exist as the adsorbed state. The dissolution behaviors as a function of cesium and potassium concentrations and pH, were also studied.
