Abstract
In this study, the photocatalytic degradation of Naphthol blue black (NBB) dye was examined under ultra violet light irradiation. Different parameters such as concentration of catalyst, dye concentration, presence of oxidising agent H2O2, pH conditions and effect of time of light irradiation were used to analyse the photocatalytic activities of Cu(II) complex. The Schiff base ligand and its metal complexes with divalent transition metal ions viz., Co(II), Ni(II), Cu(II) and Zn(II) have been synthesized and characterized through IR, 1HNMR, 13C NMR, and GC-MS. The mononuclear complexes have a 1:1 metal to ligand mole ratio, and the metal (II) ions are coordinated with the atoms of phenolic oxygen and imine nitrogen. The results showed that for photocatalytic degradation of NBB dye, Cu(II) complex of Schiff base ligand is congruous for the treatment of authentic effluents.
