Abstract: This study describe the synthesis and characterization of new azo ligand, 5-hydroxy-4-(2,4-dihydroxyphenylazo)-2,7-naphthalene disulfonic acid disodium salt (L).The Cu(II), Zn(II), Ni(II) and Co(II) complexes of the azo ligand were prepared and characterized by infrared, UVvisible, 1 H and 13 C NMR spectra, atomic absorption spectroscopy, mass spectrometry, elemental analyses, thermogravimetric analysis, conductivity and magnetic measurements.The results suggest that the complexes have a 1:1 (metal:ligand) molar ratio, involving mononuclear azo ligand with an ONO donor set.Metal ion uptake studies were conducted with a batch technique.The results indicate that the azo ligand has high thermal stability and good metal extraction capacity.
