  • Method and device for selective cation extraction by electrochemical transfer in solution and applications of said method
    Patent number: 8449747
    Abstract: In order to carry out a selective extraction of cations (Mn+) by an electrochemical transfer in a solution from a first electrolyte (E1) to a second electrolyte (E2), the method includes using as an electrolyte separation wall a transfer wall (2) made of chalcogenide with molybdenum clusters (MonXn+2 or MxMonXn+2) and ensuring the cation transfer through the transfer wall by generating a potential difference (?E) between the electrode A1 in the first electrolyte (E1) and the electrode C2 in the second electrolyte (E1) or the transfer wall (2) in order to induce an intercalation of the cations in the transfer wall on the side of the first electrolyte, a scattering of the cations therein, and the de-intercalation thereof in the second electrolyte.

  • Electrolyte separation wall for the selective transfer of cations through the wall, manufacturing process and transfer process
    Publication number: 20130126354
    Abstract: An electrolyte separation wall includes an active layer of a material capable of developing intercalation and deintercalation reactions for the selective transfer of cations through the wall and a support layer made of a porous material acting as support for the active layer. A cation selective transfer process uses such a transfer wall. According to a manufacturing process of such a transfer wall, a solution including an active material in powder form, a binder and a solvent are prepared, then the surface of a support layer made of porous material is coated with the solution and the solvent is evaporated.
