摘要：

The treatment of Slovak zeolitic tuff with different concentrations of NaOH solution creates modified forms of it. These forms exhibit an increased uptake of multivalent cations. The sorption ability of Cs+, Co2+, Cd2+, Fe3+ and Cr3+ cations was studied by gradual radioactive labelled ion-exchange and AAS methods. The influence of NaOH solutions on the structure and the surface of zeolite were studied by chemical analysis, XRD - analysis and by the measurement of the surface area of the material. DTA, TG and ETA methods were used for the studying of the influence of temperature on the natural and chemically modified zeolite. The leachability of loaded zeolitic material was also studied. Completely new matrices based on blast furnace slag were used for solidification of loaded zeolitic material.
