Langmuir-Freundlich Isotherm Analysis describes the distribution of adsorption energy onto heterogeneous surfaces of the adsorbent. At low concentrations of adsorbate, this model becomes Freundlich isotherm, and then at high concentration of adsorbate, it becomes the Langmuir Isotherm. The parameters of this concentration can be obtained using the non-linear regression.
