Abstract
Synthesis of Macrocyclic Polyamides and their Solvent Extraction and Membrane Transport Abilities for Transition Metal Ions
Reizo Dohno, Jun-lchiro Satho and Akihiko Shimura
Abstract:
Macrocycyclic ligands L,-L4 were synthesised by the high dilution method. L1 and L3 extracted efficiently only Cu2+ ion with high selectives in the competitive extraction containing CO2+, Ni2+, Zn2+ ions. Further L3 extracted quantitively Cu2+ ion even from acidic aqueous solution. The transport ability of L1 and L2 through liquid membrane were examined for several transitional metal ions.
