Synergistic Solvent Extraction of Copper (II) Ion by Using a Mixture of Imine Counting Benzedine and Palmitic or Salicylic Acid

Abstract In this research a new imine counting N2O5 donor atoms have synthesized. The new compound was prepared by reaction of 1,7-bis(6- methoxy -2- formyl phenyl)-1,4,7,10,14-penta oxa tetra decane with benzedine. The imine was purified by chromatographic column filled with silicagel, eluted with chloroform. Identification of this imine: 1,21- Diaza– [3,4-18,19- di (6,6- methoxy phenyl)]-22, 29- benzedine-5,8,11,14,17-pentaoxa cyclononaicozane 1,20-diene(II) was determined by1H- NMR (LC-MS), (IR) spectroscopy. The liquid- liquid method carried out forextraction of metalsuch as Pb(II), Ag(I),Cu(II) in presence of picrate anion. Then we carried out synergistic solvent extraction of copper (II) ion by using a mixture of imine and palmitic or salicylic acid. Organic solvents chloroform and dichloromethane were investigated at 25± 0.1oC and using atomic absorption spectrometer. The extraction percentage was calculated.
