Synthesis and Identification Some of Schiff Bases Derived From Salicylaldehyde and Determination of kinetic parameters reliance on Extraction technique

This work was focused on the synthesis of tetradentate Schiff bases which were prepared by condensation of salicylaldehyde with 1,4-diaminobenzene and 1,3-diaminobenzene. The Schiff base ligands were checked by different spectral technique (GC-MS, 1H-NMR, IR). The influences of shaking time on the extraction of Cu (II) using solvent extraction technique was studied. Then the Kinitic parameters were calculated from schemes which give best line through drawing log (a-x) vs time or 1/(a-x) vs time or [Cu2+] vs time, whereas (a-x) represents Cu(II) concentration in water phase and from it (n) reaction order, (K) reaction rate constant (t1/2) reaction half between prepared ligand and Cu (II) were calculated.
