Title
(EN) CHEMICALLY ACTIVE CERAMIC COMPOSITIONS WITH A PYROGALLOL MOIETY
(FR) COMPOSITIONS DE CERAMIQUE CHIMIQUEMENT ACTIVES A FRACTION PYROGALLOL
Abstract
(EN)
Novel ceramic compositions are used for removing metal ions by chelation from solutions such as aqueous waste streams. The compositions are formed by covalently bonding to terminal hydroxy groups of a ceramic inorganic carrier or support a substituted silane linking group attached to a chelating agent or ligand which is pyrogallol or a derivative thereof.
(FR)
De nouvelles compositions céramiques sont utilisées pour éliminer par chélation des ions métal de solutions telles que des effluents résiduaires aqueux. Les compositions sont obtenues par liaison covalente aux groupes hydroxy terminaux d'un support inorganique céramique où à un groupe de liaison silane substitué fixé à un agent de chélation qui est le pyrogallol ou un dérivé de celui-ci.
