One of the most effective method among the decontamination technologies is the adsorption removal of toxic contaminants, e.g. As, Sb, Pb, Zn, U, Cs, from aqueous systems. Aluminosilicates are known to be effective sorbents for their structural and sorption properties, availability, reasonable economic and environmental aspects. The aim of proposed project is the evaluation of waste ceramics as a potential novel sorbent of selected cationic/anionic contaminants. Its adsorption ability will be verified by batch-wise technique. The mechanism of ions sorption will be studied by means of MAS NMR spectroscopy. Since the studied sorbent has pozzolanic activity its solidification/stabilization by means of cementitious matrix is an obvious choice. The influence of adsorbed species on sorbent pozzolanic activity and course of hydration process will be also studied. The efficiency of solidification, as well as the stability of used sorbent, will be verified by leaching experiments. The project’s output will be method for toxic species elimination with help of a waste material.
