دراسة طيفية للتأثير المتبادل بين النحاس و الأورثوفينيلين ثنائي الأمين

الملخص EN

The work reports an investigation of the interaction of Cu2+ ion with the ligand o-Phenylenediamine (1,2-diaminobenzene).

Two spectrophotometric methods namely the continuous variations and the molar ratio were used.

The continuous variations was applied to determine whether, one complex or more is formed from the reaction of the metal ion Cu2+ with the ligand in a given pH value.

The results which are obtained from the pervious method was affirmed by the molar ratio method.

Moreover, the effect of the experimental variables such as pH, concentration, time and temperature upon the extent of complex formation were studied.

Also the stability constant (K) for Cu2+ complexes was calculated.
