Classification of gibbs adsorption isotherms

WebJul 9, 2002 · Classification of adsorption isotherms Most analysis of adsorption equilibria begins with classification of the isotherms. This classification is important in modeling of adsorption phenomena and for a number of practical reasons. For example, it is important for measuring surface area of adsorbents [1], [2], [3].
