  • Use of an organic-inorganic hybrid material for extracting uranium(VI) from a sulfuric acid aqueous solution, issued notably from the sulfuric leaching of a uranium-bearing ore
    Patent number: 10006103
    Abstract: The invention relates to the use of an organic-inorganic hybrid material, comprising an inorganic solid support on which are grafted organic molecules having the general formula (I) below: in which: x, y and z=0 or 1, with at least one of x, y and z different from 0; m=1 to 6; v and w=0 or 1, with v=1 when w=0, and v=0 when w=1; if x=0, R1?H or a saturated or unsaturated, linear or branched, C1 to C12 hydrocarbon group, whereas, if x=1, R1=a group bound to the inorganic solid support by at least one covalent bond; if y=0, R2?H or a saturated or unsaturated, linear or branched, C1 to C12 hydrocarbon group, whereas, if y=1, R2=a group bound to the inorganic solid support by at least one covalent bond; if z=0, R3?H or a saturated or unsaturated, linear or branched, C1 to C12 hydrocarbon group, whereas, if z=1, R3=a group bound to the inorganic solid support by at least one covalent bond; R4 and R5?H, a saturated or unsaturated, linear or branched, C2 to C8 hydrocarbon group, or a monocyclic aromatic group

  • Biological decontamination gel and method for decontaminating surfaces by using this gel
    Patent number: 9451765
    Abstract: A biological decontamination gel, consisting of a colloidal solution comprising from 5 to 30% by mass, preferably 5 to 25% by mass, still preferably 8 to 20% by mass, based on the mass of the gel, of at least one inorganic viscosifying agent: 0.5 to 10 mol/L of gel, preferably 1 to 10 mol/L of gel, of at least one active biological decontamination agent; 0.05 to 5% by mass, preferably 0.05 to 2% by mass, based on the mass of the gel, of at least one super-absorbent polymer; 0.1 to 2% by mass, based on the mass of the gel, of at least one surfactant; and the remainder of solvent. A biological decontamination method applying this gel.
