Beschreibung
Zusammenfassung:	A substantially insoluble compound having a polysaccharide backbone which is derivatised at one or more of its hydroxyl groups with a ligand (L) bound to the sugar moiety by a sulphur atom which may be tailored according to a wide range of applications. The compound is useful as a catalyst and in removal of contaminants from a feed containing particularly metal ions. L'invention concerne un composé sensiblement insoluble présentant un squelette polysaccharidique qui est dérivé au niveau d'un ou plusieurs de ses groupes hydroxyle par un ligand (L) lié à la fraction sucre par un atome de soufre qui peut être personnalisé conformément à une large gamme d'applications. Le composé est utile en tant que catalyseur et dans l'élimination de contaminants contenus dans une charge contenant en particulier des ions métalliques.
