  • Publication number: 20260021468
    Abstract: A method for preparing a geopolymer capable of trapping at least one ion, may include, firstly, preparing a geopolymer including at least one 3D printing, then functionalizing the geopolymer thus prepared by at least one extractant group, the group not including an —NH2 amine function. Such a functionalized geopolymer thus prepared may be used to separate at least one ion from a flow containing the at least one ion.

  • Publication number: 20230106358
    Abstract: Solid material having an open multiple and at least partially interconnected porosity, comprising an inorganic matrix made of a microporous and mesoporous geopolymer, in which at least partially interconnected open macropores delimited by sides or walls made of microporous and mesoporous geopolymer are defined, and particles of at least one solid compound different from the geopolymer being distributed in the macropores and/or in the sides or walls. Method for preparing said material. Method for separating at least one metal or metalloid cation from a liquid medium containing it, wherein said liquid medium is placed in contact with the material.
