Freundlich equation – Wikipedia

Category Commons Analytical Chemistry. The Freundlich equation or Freundlich adsorption isotherm istoerma, an 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.

InHerbert Freundlich gave an expression representing the isothermal variation of adsorption of a quantity of freudlich adsorbed by unit mass of solid adsorbent with pressure. K and n are constants for a given adsorbate and adsorbent at a particular temperature.

Beyond that point, the rate of adsorption saturates even after applying higher pressure. Thus, the Freundlich adsorption isotherm fails at higher pressure.
