الملخص EN

A new Schiff base (HL) derived from condensation of p-anisidine and acetyl acetone has been prepared and used as a chelating ligand to prepare Cr (III), Mn (II), Co (II), Ni (II) and Cu (II) complexes.

The study of the nature of these complexes formed in ethanol solution following the mole ratio method (2 : 1, L : M) gave results which were compared successfully with these obtained from isolated solid state studies.

These studies revealed that the complexes having square planner geometry of the type (ML2), M = Co (II), Ni (II) and Cu (II), and octahedral geometry of the type [CrIIIL2 (H2O) 2] Cl and [MNIIL2 (H2O) 2].

The adsorption studies of three complexes Cr (III), Mn (II), and Co (II) on activated carbon, H and Na-forms of purolite S-930 resin show high adsorption percentage for Cr (III) on purolite S-930 due to ion exchange interaction compared with high adsorption of neutral Mn (II), Co (II) complexes on activated charcoal.

Linear plot of log Qe versus log Ce showed that the adsorption isotherm of these three complexes on activated carbon, H and Na-forms of purolite S-930 surface obeys Freundlich isotherm and was similar to S-curve type according to Giles classification which investigates heterogeneous adsorption.

The regression values indicate that the adsorption data for these complexes fitted well within the Freundlich isothermal plots for the concentration studied.

The accuracy and precision of the concentration measurements of these complexes were determined by preparing standard laboratory samples, the results show relative error ranging from ± 1.08 to 5.31, ± 1.04 to 4.82 and ± 0.28 to 3.09 and the relative standard deviation did not exceed ± 6.23, ± 2.77 and ± 4.38 % for A1, A2 and A3 complexes, respectively.
