Distribution constant Freundlich equation Kovats retention index Retention factor Van Deemter equation. 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.

Freundlich equation – Wikipedia

This page was last edited on freeundlich Decemberat 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. From Wikipedia, the free encyclopedia.

Thus, the Freundlich adsorption isotherm fails at higher pressure. Volume 57, Issue 4, pages Gas chromatography—mass spectrometry Liquid chromatography—mass spectrometry Pyrolysis—gas chromatography—mass spectrometry. 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.
