The Freundlich equation or Freundlich adsorption isotherm, an adsorption isotherm, is an empirical relationship between the quantity of a gas adsorbed into a solid surface and the gas pressure. The same relationship is also applicable for the concentration of a solute adsorbed onto the surface of a solid and the concentration of the solute in ...
The Freundlich isotherm is the most important multi-site adsorption isotherm for rough surfaces. =, where α F and C F are fitting parameters. [14] This equation implies that if one makes a log–log plot of adsorption data, the data will fit a straight line. The Freundlich isotherm has two parameters, while Langmuir's equations has only one ...
The Langmuir isotherm is given by: [CS] = (K eq S tot [C])/(1 + K eq [C]), where S tot is the total binding molecules on the beads. The Freundlich isotherm is given by: [CS] = K eq [C] 1/n. The Freundlich isotherm is used when the column can bind to many different samples in the solution that needs to be purified.
The model applies to gases adsorbed on solid surfaces. It is a semi-empirical isotherm with a kinetic basis and was derived based on statistical thermodynamics. It is the most common isotherm equation to use due to its simplicity and its ability to fit a variety of adsorption data. It is based on four assumptions:

BET model of multilayer adsorption, that is, a random distribution of sites covered by one, two, three, etc., adsorbate molecules. The concept of the theory is an extension of the Langmuir theory, which is a theory for monolayer molecular adsorption, to multilayer adsorption with the following hypotheses:
Skin tags are benign growths, meaning they’re generally harmless. But, if it feels like one just appeared out of nowhere, you might be wondering what causes them in the first place.
