The Nigerian grass waste was used as an adsorbent for removing cobalt and zinc from the wastewater. The adsorption studies were conducted in single and binary solution. The waste was treated with sulphuric acid to enhance the properties like pore volume, particle size and surface area. The equilibrium data from the single component mode were checked with different models to investigate the adsorption mechanism. The equilibrium data were following Langmuir isotherm for cobalt and zinc. The adsorption in the binary solution mode showed synergism signifying that the addition of a component to a system increases the total adsorption capacity of the system.
