1,2,4-triazoles ring containing of two different ligand using spectroscopic apporach investigation of complexation properties with metal cation

In this study, the complexation properties of 4-{[3,5 di-phenyl-4H-1,2,4-triazole-4yl]amino]methy}phenol (Ligand 1) and 1-{[3-methyl-5-(4-methylphenyl)-4H-1,2,4-triazol-yl]amino)methyl-2 naphthol (Ligand 2) with metal cations were investigated by using spectrophotometric methods. The complex stability constants of Co2+, Ni2+, Cu2+, Pb2+ and Cd2+ with both ligands were determined according to Buschmann?s and Valeur?s methods. At the same time, the usability of the the Ligand 2 to assay metal cations was investigated.
