Title (EN) GRAPHENE-BASED FILTERING ELEMENT AND USES THEREOF
(FR) ÉLÉMENT DE FILTRAGE À BASE DE GRAPHÈNE ET SES UTILISATIONS
Abstract:
(EN) The present invention relates to a filtering element comprising a blend of mesoporous graphene compound having pores with average pore size between 0,4 and 250 nm and at least one spacing material in granular form having an average particle size between 0,1 and 6 mm wherein the contribution of pores having an average pore size from 2 and 50 nm to the total specific surface area of the mesoporous graphene compound is not less than 50% of the total specific surface area and wherein the minimum density of the filtering element is at least the 15% of the bulk density of the spacing material. The invention further relates to a method for the removal or separation of contaminants from a fluid and a method for in-situ groundwater remediation with the filtering element. Furthermore, the invention relates to a filtration mask and a cartridges comprising the filtering element.
(FR) La présente invention concerne un élément de filtrage comprenant un mélange de composé de graphène mésoporeux ayant des pores ayant une taille de pore moyenne comprise entre 0,4 et 250 nm et au moins un matériau d'espacement sous forme granulaire ayant une taille de particule moyenne comprise entre 0,1 et 6 mm, la contribution des pores ayant une taille de pore moyenne de 2 à 50 nm à la surface spécifique totale du composé de graphène mésoporeux n'est pas inférieure à 50 % de la surface spécifique totale et la densité minimale de l'élément de filtration étant au moins égale à 15 % de la densité apparente du matériau d'espacement. L'invention concerne en outre un procédé d'élimination ou de séparation de contaminants à partir d'un fluide et un procédé d'assainissement in-situ de l'eau souterraine avec l'élément de filtrage. En outre, l'invention concerne un masque de filtration et des cartouches comprenant l'élément de filtrage.
