METHOD FOR RECOVERING METAL IONS FROM INDUSTRIAL WASTE WATER, AND USE ASSOCIATED THEREWITH OF A COMPLEXING AGENT

The present invention relates to a method for recovering metal ions from industrial waste water by: - bringing the industrial waste water into contact with siderophores, thereby producing a metal ion-siderophore complex, characterised in that the siderophores are covalently immobilised on a support...

Beschreibung
Zusammenfassung:	The present invention relates to a method for recovering metal ions from industrial waste water by: - bringing the industrial waste water into contact with siderophores, thereby producing a metal ion-siderophore complex, characterised in that the siderophores are covalently immobilised on a support material by means of a linker, the linker containing a polyethylene glycol chain and said linker having a mass of 2000-3500 Da, and also relates to the use, in this method, of a complexing agent having a support material, on which siderophores are covalently immobilised by means of a linker, the linker containing a polyethylene glycol chain and said linker having a mass of 2000-3500 Da.
