Title (EN) SOLID NANOCOMPOSITE MATERIAL MADE FROM HEXA- OR OCTACYANOMETALLATES OF ALKALI METALS, METHOD FOR PREPARING SAME, AND METHOD FOR EXTRACTING METAL CATIONS
(FR) MATERIAU SOLIDE NANOCOMPOSITE A BASE D'HEXA- OU OCTACYANOMETALLATES DE METAUX ALCALINS, SON PROCEDE DE PREPARATION, ET PROCEDE D'EXTRACTION DE CATIONS METALLIQUES
Abstract:
(EN) The invention concerns a solid nanocomposite material comprising nanoparticles of a hexacyanometallate or octacyanometallate of an alkali metal and a transition metal, of formula [Alk+ x]Mn+ [M'(CN)m] z- in which Alk is an alkali metal, x is 1 or 2, M is a transition metal, n is 2 or 3, M' is a transition metal, m is 6 or 8, z is 3 or 4, attached to at least one surface of a porous inorganic solid support, in which the nanoparticles are attached by adsorption to said at least one surface of the solid support, and in which said surface is a basic surface. The invention also concerns a method for preparing this material, and a method for extracting at least one metal cation from a liquid medium containing it, that involves bringing said liquid medium into contact with said material.
(FR) L'invention concerne un matériau solide nanocomposite comprenant des nanoparticules d'un hexacyanométallate ou octacyanométallate d'un métal alcalin et d'un métal de transition, répondant à la formule [Alk+ x]Mn+ [M'(CN)m] z- où Alk est un métal alcalin, x est 1 ou 2, M est un métal de transition, n est 2 ou 3, M' est un métal de transition, m est 6 ou 8, z est 3 ou 4, fixées à au moins une surface d'un support solide inorganique poreux, dans lequel les nanoparticules sont fixées par adsorption à ladite au moins une surface du support solide, et dans lequel ladite surface est une surface basique. Elle concerne également un procédé de préparation de ce matériau, et un procédé pour extraire au moins un cation métallique à partir d'un milieu liquide le contenant, dans lequel on met en contact ledit milieu liquide avec ledit matériau.
