Title (EN) GRAFTED POROUS CYCLODEXTRIN POLYMERIC MATERIAL AND METHODS OF MAKING AND USING SAME
(FR) MATÉRIAU POLYMÈRE À BASE DE CYCLODEXTRINE POREUX GREFFÉ ET PROCÉDÉ DE FABRICATION ET D'UTILISATION DE CELUI-CI
Abstract:
(EN) Provided herein are compositions comprising mesoporous cyclodextrin (CD) containing polymers grafted to or bonded to a substrate. The compositions can be used for removing organic contaminants from water. The P-CDPs can rapidly sequester pharmaceuticals, pesticides, and other organic micropollutants, achieving equilibrium binding capacity in seconds with adsorption rate constants 15-200 times greater than activated carbon and nonporous CD sorbents. The composition can be regenerated several times, through a room temperature washing procedure, with no loss in performance.
(FR) La présente invention concerne des compositions comprenant des polymères mésoporeux contenant de la cyclodextrine (CD) greffés sur un substrat ou liés à celui-ci. Les compositions peuvent être utilisées pour éliminer des contaminants organiques de l'eau. Les P-CDP peuvent rapidement séquestrer des produits pharmaceutiques, des pesticides et d'autres micro-polluants organiques, ce qui permet d'atteindre la capacité de liaison à l'équilibre en quelques secondes avec des constantes de vitesse d'adsorption 15 à 200 fois supérieures à celles de sorbants en charbon actif et de sorbants à base de cyclodextrine non poreux. La composition peut être régénérée à plusieurs reprises, par une procédure de lavage à température ambiante, sans perte de performance.
