  • Organosilicon material for the decontamination of water
    Patent number: 10799850
    Abstract: The subject of the present invention is the use of a porous or non-porous organosilicon material for eliminating radionuclides, mineral anions, anionic molecular entities and negatively charged dyes or active principles from an aqueous solution, characterized in that the structure of said organosilicon material is formed of repeat units, each repeat unit comprising at least one positively charged entity selected from an ammonium entity, an imidazolium entity, a guanidinium entity, a pyridinium entity and a phosphonium entity and being incorporated into a silicon network by at least two silicon-carbon bonds. The invention also relates to a specific novel organosilicon material, comprising at least one benzyl group, one 4-phenylbenzyl group or one styrene group in each repeat unit.
