Freundlich Isotherm Model
Description
The Freundlich isotherm describes adsorption on heterogeneous surfaces and assumes that stronger binding sites are occupied first (Freundlich, 1907). The model is empirical and is expressed by the equation:
Q = K_f \cdot C_e^{1/n}
where Q
is the amount adsorbed, C_e
is the equilibrium concentration,
K_f
is the Freundlich constant related to adsorption capacity, and n
is the heterogeneity factor
(indicating adsorption intensity).
