Özet:

 

Adsorption equilibria were analyzed on the basis of general  equilibrium constant expression for the development of fundamental  adsorption equations (Freundlich, Langmuir, and BET) in connection  with the establishment of a general approach towards physical  interpretations of adsorption parameters.  Theoretically it was proved  that Freundlich plot analysis cannot be used to find useful parameters  such as the monolayer adsorption capacity of an adsorbent.  The  present theory also indicated that the adsorption process with known  value of monolayer adsorption capacity can be studied for finding  various equilibrium constants on the basis of the Fronaeus equation,  which is commonly used in the complexation process.  The applications  of the Langmuir equation in finding the ligand number of a complex as  well as the magnitude of equilibrium constant required for the  analysis of the BET equation in the multilayer liquid phase adsorption  process was also discussed.  It was concluded that the general  approach towards exploration and physical interpretation of adsorption  parameters can be developed by analyzing the adsorption equilibria on  the basis of general equilibrium constant expression in accordance  with the law of mass action.
