Synthesis, Characterization and Metal PicrateExtraction Studies of Salicylaldehyde DerivedMacrocyclic Schiff Bases

摘要

Three novel Salicylaldehyde derived macrocyclic Schiff bases were synthesized and well characterized by Elemental analyses, IR, Mass and 1HNMR spectral data. The liquid-liquid extraction of metal cations (Ag+ and Cu2+) 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.
