Cesium adsorption isotherm on swelling high-charged micas from aqueous solutions: Effect of temperature

The potential use of a new family of synthetic swelling micas for cesium immobilization from aqueous solution was evaluated and the structural modifications after adsorption were analyzed. The results have revealed that they are good cesium adsorbents compared to natural clays and as the layer charg...
