Abstract
Nanofibres are provided that are insoluble and swellable in an essentially aqueous effluent, a method for the preparation of these nanofibres and the use of these nanofibres for the extraction from an effluent of metals, in particular metal salts originating from heavy metals, of rare earths, alkali metals, alkaline earth metals or actinides, in the stable or unstable isotopic forms thereof.
