Beschreibung
Zusammenfassung:	Method for treating a material comprising at least one organic compound capable of releasing undesirable anions while being thermally and/or chemically and/or physically treated, the method comprising at least one step in which the material is brought into contact with a dense pressurised aqueous medium (which is in particular subcritical or supercritical) or with a pressurised aqueous medium in the form of steam, in the presence of a material which is reactive to the undesirable anions and capable of immobilising the undesirable anions in its structure, whereby the organic compound is destroyed, being at least partially mineralised; at the same time, the undesirable anions are released, and immediately captured and then immobilised, by the solid material which is reactive to the undesirable anions, and an undesirable anion-free aqueous solution is produced.
