摘要：

The present work deals with the study of uptake behavior of cesium ions by polyaniline applying a radiotracer technique. The parametric study reveals that the increase of adsorbate concentration (10(-8) to 10(-3) mol dm(-3)) and temperature (303 to 333 K) enhances the removal of the ions and from thermal and kinetic data it is inferred that the adsorption of cesium ions follows first order rate law, obeys Freundlich isotherm and is endothermic in nature. The radiation stability of polyanifine was also investigated by exposing it to a 11.1 GBq (Ra-Be) source associated with gamma dose of 1.72 Gyh(-1).
