Useful Adsorption Equilibriums by Means of Natural Clay
Abstract
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.
