WebbTo a first approximation this dependence is linear, yielding adsorption isotherms that retain the Langmuir form but have a different interpretation of the constants from that given by Langmuir. A much better approximation is obtained by a quadratic fit which gives adsorption isotherms of the form: c_s = \frac { {f \cdot p}} { {f'' p^2 + p + f'}} WebbThree isotherm models are given in recent literature in order to fit the experimental equilibrium data: the Langmuir equation Equation (1) [47], the Freundlich equation Equation (2) [48] and the combinational Langmuir-Freundlich (L-F) equation Equation (3) isotherm model [49]: m L e e Le K = 1 + K QC Q C (1) 1/n QC e F e = K (2) 1/b 1/
