  • Supported membrane functionalized with hexa- and octacyanometallates, process for the preparation thereof and separation process using same
    Patent number: 10068676
    Abstract: A supported membrane is provided comprising an inorganic, solid porous filtration membrane supported by an inorganic, solid porous support, said supported membrane comprising nanoparticles of a metal coordination polymer with CN ligands comprising Mn+ cations, where M is a transition metal and n is 2 or 3; and Alk+y[M?(CN)m]x? anions where Alk is an alkaline metal, y is 0, 1 or 2, M? is a transition metal, x is 3 or 4, and m is 6 or 8; said Mn+ cations of the coordination polymer being bound through an organometallic or coordination bond to an organic group of an organic graft chemically attached to the surface of the filtration membrane, inside the pores of the filtration membrane, and optionally inside the pores of the support. The supported membrane may be used in a process for separating at least one metal cation and solid particles from a liquid medium containing the same.

  • Nanocomposite solid material based on hexa- and octa-cyanometallates, method for the preparation thereof and method for fixing mineral pollutants using said material
    Patent number: 9786398
    Abstract: A nanocomposite solid material includes nanoparticles of a metal coordination polymer with CN ligands comprising Mn+ cations, in which M is a transition metal and n is 2 or 3; and anions [M?(CN)m]x? in which M? is a transition metal, x is 3 or 4, and m is 6 or 8. The Mn+ cations of the coordination polymer are bound through an organometallic bond to an organic group of an organic graft chemically attached inside the pores of a support made of porous glass. The material can be used in a method for fixing (binding) a mineral pollutant, such as radioactive cesium, contained in a solution by bringing the solution in contact with the nanocomposite solid material.

  • NANOCOMPOSITE SOLID MATERIAL BASED ON HEXA- AND OCTA- CYANOMETALLATES, METHOD FOR THE PREPARATION THEREOF AND METHOD FOR FIXING MINERAL POLLUTANTS USING SAID MATERIAL
    Publication number: 20120125856
    Abstract: A nanocomposite solid material includes nanoparticles of a metal coordination polymer with CN ligands comprising Mn+ cations, in which M is a transition metal and n is 2 or 3; and anions [M?(CN)m]x? in which M? is a transition metal, x is 3 or 4, and m is 6 or 8. The Mnn+ cations of the coordination polymer are bound through an organometallic bond to an organic group of an organic graft chemically attached inside the pores of a support made of porous glass. The material can be used in a method for fixing (binding) a mineral pollutant, such as radioactive cesium, contained in a solution by bringing the solution in contact with the nanocomposite solid material.
