Beschreibung
Zusammenfassung:The invention relates to a metal ion extractant material for use in the extraction of metal ions from a solution or slurry, the extractant material being based on an ethyleneimine-containing polymer. The ethyleneimine-containing polymer may be attached to a solid substrate which may optionally be ground to form a particulate extractant material. Alternatively, an ethyleneimine-containing polymeric material may be cross-linked and subsequently ground to form a particulate metal ion extractant material without the need for a solid substrate.
