A process for the reduction of the heavy metal contents of heavy metal-containing combustion - and pyrolysis residues

摘要

the invention concerns a method for reducing heavy metals from waste containing incineration and pyrolyseru00fcckstu00e4nden using aqueous solvent.the invention has the purpose of $a, the heavy metal content and thus significantly reduce the toxicity.$a is solved this task by scrubbing of waste containing residues with an aqueous solution of the chelating agent with at least two metallkoordinierenden moleku00fclgruppen contains.
