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.
