Freundlich isotherm example
Webof sorption behavior. This isotherm is termed the "Freundlich Isotherm". It is described by: 1/n q= Kc Feq (4) Where K F is the "Freundlich" equilibrium constant and 1/n is an arbitrary constant evaluated by linearizing the equation. If (1/n) approaches 1 the equation is linear. For non-linear isotherms the data can be WebThe adsorption isotherm model was fitted by Langmuir and Freundlich equations: (1) Langmuir model: C e /Q e = 1/(Q max *K L) + C e /Q max (2) Freundlich model: lnQ e = lnK F + (lnC e)/n. Q max represents the maximum adsorption capacity, K L and K F represent the adsorption coefficient and equilibrium constant, respectively. 2.3.2. Kinetic ...
