Derivation of the Freundlich Adsorption Isotherm from Kinetics
Skopp, Joseph
Journal of Chemical Education, v86 n11 p1341-1343 Nov 2009
The Freundlich adsorption isotherm is a useful description of adsorption phenomena. It is frequently presented as an empirical equation with little theoretical basis. In fact, a variety of derivations exist. Here a new derivation is presented using the concepts of fractal reaction kinetics. This derivation provides an alternative basis for interpreting the parameters obtained using the Freundlich isotherm. The derivation is simple enough to be used in an undergraduate chemistry class. The derivation can also be extended to a fractal-like Langmuir adsorption isotherm.
