Composite solid material of the mineral contaminants a base of hexacyanoferrates and the polymer in the film layer, its process of preparation, and method of attachment of the mineral the pollutants using
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.
