Abstract

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.

 

Keywords: Macrocyclic Schiff bases, metal cation extraction, solvent partitioning
