Abstract
The results of cesium recovery from seawater with commercially available Termoxid sorbents (Termoxid 35, Termoxid 3A) under laboratory and expeditionary conditions are presented. The dynamic exchange capacity and the total dynamic exchange capacity of the sorbents for cesium were determined. The breakthrough curves of cesium sorption were plotted for different seawater flow rates, and the physicochemical relationships (isotherm and kinetics) of sorption were studied. The efficiency of 137Cs recovery from large volumes of seawater by Termoxid sorbents under expeditionary conditions was evaluated.
