Synthesis of N2O2S2-Schiff base Ligand and Using it to Transport Cu2+ Through Bulk Liquid Membrane

New Schiff base (H2L) containing nitrogen-sulfur-oxygen atoms was synthesized by reaction of α,α -bis(5- Bromo-2-carboxyaldehyde phenoxy)-1.4- xylene with aminothiophenol. Transport of copper ion across a bulk chloroform membrane containing Schiff base ligand (H2L) as carrier has been studied. The parameters influencing the transport efficiency such as composition of receiving phase, pH of the feed phase, carrier concentration in the membrane, EDTA concentration in the receiving phase, effect of temperature and time dependency of the process were studied and discussed. The amount of copper transport through the liquid membrane after 48 min., arrived to 100% at temperature 58°C.
