Description
| - Článek pojednává o studiu sorpce cesia na směsi vybraných jílů s pískem, o nichž se uvažuje jako možném zásypovém materiálu úložišť aktivních odpadů. Byl zjištěn nárůst distribučních poměrů (Rd) s rostoucím podílem jílu ve směsi a byly také zjištěny významné rozdíly mezi přirodními a technologicky modifikovanými jíly. (cs)
- he adsorption of cesium on various smectite-rich clays was studied as a function of the initial concentration of cesium and in the presence of competitive ions (Na+, K+ and Ca2+) using the radiotracer method, examining the effects of the clay structure and comparing the behaviour of bentonites with that of sedimentary clays. The experiments were performed under laboratory conditions, at 22-25 degrees C, in ambient atmosphere and using synthetic average granite groundwater as the liquid phase. Reference smectites (STx-1, SAz-1), illite (IMt-1) and kaolinite (KGa-2), three Czech smectite-rich clays (bentonite from Rokle, sedimentary clays from Skalna and Marsov) and three Spanish bentonites from Cabo de Gata were used as the natural sorbents. The adsorption data were fitted by the Freundlich isotherm. Smectites exhibited the highest values of the adsorption capacity and the highest affinity for cesium within the studied concentration range, 10(-6) to 10(-1) M.
