Title (EN) METHOD OF PRODUCING A FILTERING MATERIAL OF NATURAL ORIGIN AND FILTERING MATERIAL THUS OBTAINED
(FR) PROCÉDÉ DE FABRICATION D'UN MATÉRIAU FILTRANT D'ORIGINE NATURELLE ET MATÉRIAU FILTRANT AINSI OBTENU
Abstract:
(EN) A method is described for producing a filtering material of natural origin, which uses raw wool as the starting material, which is washed, degreased and then subjected to a microwave treatment capable of breaking a part of the disulfide bridges present in the keratin of the wool, making them available for bonding with metals. The use of the filtering material obtained with the method of the present invention for the removal of metals, in particular arsenic and chromium, from liquid effluents is also described.
(FR) L'invention concerne un procédé de production d'un matériau filtrant d'origine naturelle utilisant comme matière première de la laine brute qui est lavée, dégraissée puis soumise à un traitement par micro-ondes capable de rompre une partie des ponts disulfures présents dans la kératine de la laine, les rendant aptes à la liaison avec des métaux. Est également décrite l'utilisation du matériau filtrant obtenu avec le procédé de la présente invention pour l'élimination de métaux, en particulier l'arsenic et le chrome, à partir d'effluents liquides.
