| Abstract This work included the Synthesis and characterization tetra dentate Schiff base Ligand (Na2L) contaning (N2 and O2) as donor atoms type (N2O2) . This Ligand was prepared by reaction of 1,2- phenylen diamine with sodium pyruvate under reflex in methanol and drops of CH3COOH gave the Ligand (Na2L). The extraction of zinc(II) with above ligand has been studied . The effect of different parameters such as type of medium and time of equilibration, concentration of metal ion, type of organic solvent and effect temperature. The function of thermodynamic (∆S, ∆G, ∆H) was calculated. The stoichiometry of the extract species was determined using three methods such as slope analysis, mole retio and Job's methods and found to be (M:L) (1:1). The system found to be effective in separating milligram amounts of Zn(II) and in determining trace amount of Zn(II) spectrometrically. | ||
