In the present work, Schiff base ligand has been synthesized from synthesized dialdehyde and primary amine. The synthesized ligand and its copper metal complex were characterized by melting point & spectral analysis such as IR, 1 HNMR, 13 C and GC-MS. In the presence of H 2 O 2 as an oxidising agent the photocatalytic performance of the complex was assessed by the photodegradation of dyes. By carrying spectrophotometrically on irradiation of visible light using Cu(II) metal complex of Schiff base ligand the photocatalytic degradation of Naphthol Blue Black dye (NBB), Rhodamine B (RB) and Methylene Blue (MB) dyes was carried out. The photocatalytic degradation of NBB, RB and MB dyes was carried out with reference to effect of time. The results revealed that Cu-complex of Schiff base ligand is consistent for photocatalysis of these dyes for treatment of authentic effluents. The results show that the optimal dose for maximal degradation of these dyes was found to be 5 mgL -1 of the Cu(II) metal complex. The % degradation of NBB, RB and MB were found to be 55%, 50% and 80% in the visible light irradiation. The % degradation of MB dye was greater as compare to other two dyes. The order of % degradation of three dyes by copper metal complex was found as MB > NBB >RB
