MATERIAU SOLIDE COMPOSITE FIXANT DES POLLUANTS MINERAUX A BASE D'HEXACYANOFERRATES ET DE POLYMERE EN COUCHE PELLICULAIRE, SON PROCEDE DE PREPARATION, ET PROCEDE DE FIXATION DE POLLUANTS MINERAUX LE METTANT EN OEUVRE

摘要

The invention concerns a composite solid material fixing polluting minerals, based on metal hexacyanoferrate, characterised in that it comprises a solid support coated with an anion-exchanging polymer film to which is fixed an insoluble metal hexacyanoferrate composite solid material forming a thin layer. The invention also concerns a method for preparing said composite solid material fixing polluting minerals based on hexacyanoferrates. Finally the invention concerns a fixing method which can be continuously carried out in column of at least one polluting mineral contained in a solution, on said composite solid material fixing polluting minerals. Said solution is in particular a liquid or an effluent derived from industry or nuclear installations.
