Abstract
Řešení poskytuje kompozitní materiál obsahující stabilizované vysokovalentní železo, který obsahuje matrici a vodorozpustné železičitany, železičnany a/nebo železany. Matrice je zejména na bázi anorganických látek, v jednom výhodném provedení může být matricí neutralizační kal z čistíren důlních vod. Tento kompozitní materiál je zejména vhodný pro čištění a dezinfekci povrchových, podzemních a/nebo odpadních vod. Dále řešení poskytuje způsob přípravy kompozitního materiálu, kdy se matrice se zabudovanými ionty železa v oxidačním stavu 2+ nebo 3+ nebo jejich směsí podrobí žíhání a/nebo alkalickém tavení v přítomnosti oxidačního činidla.The present invention provides a composite material comprising a stabilized high-grade iron that includes a matrix and water-soluble ferrates, ferrates and / or ferrates. In particular, the matrix is based on inorganic substances, in one preferred embodiment the matrix may be a neutralizing sludge from mine water treatment plants. This composite material is particularly suitable for cleaning and disinfecting surface, ground and / or waste water. Further, the present invention provides a method of preparing a composite material wherein the matrix with incorporated iron ions in the 2+ or 3+ oxidation state or a mixture thereof is subjected to annealing and / or alkaline melting in the presence of an oxidant.
