This paper summarizes the conclusions of experiments conducted on the adsorption of Co3+ onto zeolite. The focus of the experiments was to establish the influence of the initial concentration of the metal ion solution on adsorption capacity of zeolite. Langmuir and Freundlich isotherm models were used to validate the experimental data. Adsorption isotherms of Co (III) ions obey the Langmuir equation that indicates the monolayer sorption of Co (III). The findings from this study on the cobalt adsorption behavior of nanostructure of zeolite may have potential applications in wastewater and water purification works
