| Abstract | ||
| This paper reports the specific and uphill transport of Cu (II) ions across a liquid membrane [CH2 Cl2 – C2H4Cl2 ] mediated by a tetradendate Schiff base ligands as carriers .The transport is driven by pH gradient between two aqueous phase (source and receiving phase ) and the cation transfer has been coupled by a counter flow of protons .The concentration of metal ions in SP(source phase ) , and RP(receiving phase ) monitored by spectrophotometric method and was found to decrease progressively in SP, whereas Cu (II) ions appeared in RP and their concentration increased with time . | ||
