This study is based on the investigation of the adsorption property of Methylene blue onto Co3O4 as a surface. the optimum conditions of this study were determind and it was found that the dose of Co3O4 was 50 mg, the pH of adsorption dye was 10, the initial concentration of dye was 15 mg/L, and temperature found to be 45 C°. Langmuir and Freundlich isotherm models were used for investigating the equilibrium adsorption of Methylene blue dye onto Co3O4 . The thermodynamic study shows that the adsorption of the MB dye process was non-spontaneous and endothermic under the studied conditions.
