Abstract

Three novel Salicylaldehyde derived macrocyclic Schiff bases were synthesized and well characterized by Elemental analyses, IR, Mass and HNMR spectral data. The liquid-liquid extraction of metal cations (Ag and Cu) from aqueous phase to organic phase was carried out using these ligands. The effect of chloroform and dichloromethane as organic solvents over the metal picrate extraction was investigated at 25±0.1oC by using atomic absorption spectrometer.
