In this study, cobalt oxide (Co3O4) was prepared by thermolysis of cobalt (II) oxalate at ???????????? This oxide was characterized by IR spectroscopy, XRD (X-ray diffraction) and SEM (scanning electron microscopy). The adsorption of phenol and lead (II) ions, both singly and in combination, by obtained and characterized Co3O4 was studied in batch system. Kinetic and equilibrium experiments were conducted to study the effects of solid : liquid ratio, pH, contact time and initial concentration of the pollutants. Th...
