Equilibrium isotherms have been determined for the adsorption of nickel onto natural clay. The experimental results have been fitted using the Freundlich, Langmuir and Redlich-Peterson isotherms. The maximum adsorption capacity of the clay was found to be 12.5 mg/g. The relative costs of nickel removal are reported based on adsorption capacity alone and are found to be 2.8% of that of activated carbon.
