1. A method for extraction of compounds comprising one or more metal or metalloid from an aerial or aqueous medium by selective binding, said method comprising:
providing an aerial or aqueous medium comprising compounds comprising one or more metal or metalloid;
exposing said aerial or aqueous medium to a composite, said composite comprising at least one porous template functionalized by at least one polymer, said polymer comprising one of the following chemical functions: primary, secondary or tertiary amine, amide, nitrile, pyridine, pyrrole, thiol, thiolether, thiophene, thiadiazole, alcohol/hydroxyl, phenol, catechol, pyragallol, carboxylic acid, aldehyde, ester, acyl, crown ether, phosphate, phosphoryl, epoxide, halogen, haloalkane;
during said exposure, allowing the compounds comprising one or more metal or metalloid to bind to the composite.
