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 it is in contact.

This page was last edited on 29 Decemberat Retrieved from ” https: InHerbert Freundlich gave an expression representing the isothermal variation of adsorption of a quantity of gas adsorbed by unit mass of solid adsorbent with pressure. Category Commons Analytical Chemistry.

Distribution constant Freundlich equation Kovats retention index Retention factor Van Deemter equation. Gas chromatography—mass spectrometry Liquid chromatography—mass spectrometry Pyrolysis—gas chromatography—mass spectrometry. Thus, the Freundlich adsorption isotherm fails at higher pressure.

Beyond that point, the rate of adsorption saturates even after applying higher pressure.

Volume 57, Issue 4, pages 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 freunvlich use such isotherms instead see for example the Langmuir and BET adsorption theories.

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. Views Read Edit View history.
