Abstract
Macrocyclic ligands have been studied as cation carriers in a supporte d liquid membrane system. Cd2+ has been transported using nitrogen sub stituted macrocycles as carriers and several divalent metal ions (M(2)=Zn, Co, Ni, Cu, Pb, Mg, Ca, and Sr) have been transported using DBN3 O2, DBN2O2 and PolyNtnoen as carriers in a supported liquid membrane s ystem. Competitive Cd2+-M(2+) transport studies have also been carried out with the same system. Ligand structure, stability constant, membr ane solvent and carrier concentration are also important parameters in the transport of metal ions.
