摘要
In a method for reducing the leaching of oxyanion forming elements, in particular chromium, from materials containing environmentally noxious constituents, especially from incineration residues, especially flue gas cleaning products from waste incineration, in particular fly ash, the said materials are admixed with an aqueous medium such as water in a closed container in a liquid-solid ratio sufficient to cause reducing conditions capable of stabilizing oxyanion forming elements, in particular chromium, due to oxidation of metallic Al, Zn, Fe, and other free metals present in the said materials.
