摘要：

Micelle-solubilized extractants have large possibilities in the field of metal recovery. A new application, based on the very slow rates of complexation observed between hydrophobic extractants (7-(4-ethyl-1-methyloctyl)-8-hydroxyquinoline) solubilized in cationic micelles (CTAB) and transition-metal ions (especially Ni2+ and Co2+), is suggested. It concerns the achievement of a selective separation of metal ions on the basis of their kinetics of complexation. The effectiveness of dialysis and ultrafiltration membrane processes for Ni2+/Co2+ separation is compared. They can lead to a total removing of Co2+ ions.
