A. Akgerman and M. Zardkoohi (J. Chem. Eng. Data 41,185 (1996)) examined the adsorption of phenol from aqueous solution on to fly ash at 20°e. They fitted their observations to a Freundlich isotherm of the form Cads=KCI where Cads is the concentration of adsorbed phenol and c sol is the concentration of aqueous phenol. Among the data reported are the following: Determine the constants K and n. What further information would be necessary in order to express the data in terms of fractional coverage, θ?
