Beschreibung
Zusammenfassung:	he present invention relates to a composite for extracting one or more metal or contaminating chemical species from an aerial or aqueous medium by selective binding, said composite comprising at least one porous template functionalized by at least one polymer, said polymer comprising one of the folowing chemical functions: primary, secondary or tertiary amine, amide, nitrile, pyridine, pyrole, thiol, thiolether, thiophene, thiadiazole, alcohol/hydroxyl, phenol, catechol, pyragalol, carboxylic acid, aldehyde, ester, acyl, crown ether, phosphate, phosphoryl, epoxide, halogen, haloalkane. La présente invention concerne un composite permettant d'extraire une ou plusieurs espèces chimiques métalliques ou contaminantes à partir d'un milieu aérien ou aqueux par liaison sélective, ledit composite comprenant au moins un gabarit poreux fonctionnalisé par au moins un polymère, ledit polymère comprenant l'une des fonctions chimiques suivantes: amine primaire, secondaire ou tertiaire, amide, nitrile, pyridine, pyrole, thiol, thioléther, thiophène, thiadiazole, alcool/hydroxyle, phénol, catéchol, pyragalol, l'acide carboxylique, l'aldéhyde, l'ester, l'acyle, l'éther couronne, le phosphate, le phosphoryle, l'époxyde, l'halogène, l'haloalcane.
