Use of a material based on organic and/or inorganic fibres and chitosan for fixing metal ions

   
   

The invention concerns the use of a material based on organic and/or inorganic fibres and chitosan for fixing metal ions contained in an effluent. The invention is characterised in that chitosan represents between 0.01 and 20% by dry weight of fibres and its degree of deacetylation is higher than 90%.

L'invention concerne l'utilisation d'un matériel basé sur les fibres organiques et/ou inorganiques et chitosan pour les ions de réparation en métal contenus dans un effluent. L'invention est caractérisée du fait chitosan représente entre 0.01 et 20% par le poids sec de fibres et son degré de deacetylation est plus haut que 90%.
