Title
(EN) SWELLABLE AND INSOLUBLE NANOFIBRES AND USE THEREOF IN THE TREATMENT OF ESSENTIALLY AQUEOUS EFFLUENTS
(FR) NANOFIBRES GONFLABLES ET INSOLUBLES ET LEUR UTILISATION DANS LE TRAITEMENT DES EFFLUENTS ESSENTIELLEMENT AQUEUX
Abstract
(EN)
The invention relates to nanofibres that are insoluble and swellable in an essentially aqueous effluent, to a method for producing said nanofibres, and to the use of said nanofibres for extracting the metals in an effluent, particularly the metallic salts of heavy metals, rare earths, alkaline metals, alkaline earths or actinides, in their stable or unstable isotopic forms.
(FR)
La présente invention concerne des nanofibres insolubles et gonflables dans un effluent essentiellement aqueux, une méthode de préparation de ces nanofibres et l'utilisation de ces nanofibres pour l'extraction dans un effluent des métaux, notamment les sels métalliques issus des métaux lourds, des terres rares, des métaux alcalins,des alcalinoterreux ou des actinides, dans leurs formes isotopiques stables ou instables.
