ISOTERMA DE FREUNDLICH PDF

As this relationship is entirely empirical, in the case where adsorption behavior can be properly fit by isotherms with a theoretical basis, it is usually appropriate to use such isotherms instead see for example the Langmuir and BET adsorption theories. Category Commons Analytical Chemistry. K and n are constants for a given adsorbate and adsorbent at a particular temperature. By using this site, you agree to the Terms of Use and Privacy Policy.

The Freundlich equation or Freundlich adsorption isotherman adsorption isothermis an empirical relation between the concentration of a solute on the surface of an adsorbent to the concentration of the solute in the liquid with which issoterma is in contact.

It is used in cases where the actual identity of the solute is not known, such as adsorption of colored material from sugar, vegetable oil etc. Distribution constant Freundlich equation Kovats retention index Retention factor Van Deemter equation. Thus, the Freundlich adsorption isotherm fails at higher pressure.
