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...

In this study, the adsorption behavior of natural zeolites (clinoptilolite) with respect to Cs+ has been studied in order to consider its application to purity radioactive wastewater. The natural zeolite was activated in two steps. In the first step with a 2 M HCl solution and then with 2 M NaOH solution. The natural and the chemical treated zeolite was subjected to FTIR spectroscopy, XRD (X-ray diffraction) and SEM (scanning electron microscopy) and EDX analysis. The batch method and column studies have been empl...
