Description	Byla syntetizována nová slída, Cs-tetra-ferri-annit. Její vlastnosti byly zkoumány z hlediska imobilizace radionuklidů; Cs. Byly provedeny loužící testy za různých podmínek. Alumosilikáty jsou potencionálním adeptem pro imobilizaci Cs. (cs) Recently, a new mica phase Cs-tetra-ferri-annite has been synthesized and studied. This phase has been investigated because its high structural stability and assumed associated low leachability for Cs suggest that it may be a suitable waste form for immobilization of Cs. Further, synthesis, under hydrothermal conditions, is possible under conditions typical of an industrial-scale immobilization plant. Consequently, cesium-tetra-ferri-annite can be considered as a waste form for the fixation of Cs from solid radioactive waste. In this study, Cs immobilization in Cs-tetra-ferri-annite and CsAlSiO4, as well as sorption onto montmorillonite and zeolite 13X, have been studied. Experiments were carried out to determine the influence of pH, temperature, time and leaching technique on the extent of release of Cs from these solids.
