One hundred years of the Ostwald—de Izaguirre theory for adsorption from solution. Its connection with carbon adsorbents

On the occasion of its first centenary, a brief account on the theory developed in 1922 by Wolfgang Ostwald and Ramón de Izaguirre for adsorption from solution is presented. An overview of the theory, including the role of animal—derived carbons in its validation, is followed by an assessment of its...

Sumario:On the occasion of its first centenary, a brief account on the theory developed in 1922 by Wolfgang Ostwald and Ramón de Izaguirre for adsorption from solution is presented. An overview of the theory, including the role of animal—derived carbons in its validation, is followed by an assessment of its impact in the field of adsorption by carbons. Two main outcomes of the theory are the first classification of adsorption isotherms (currently displaced by Giles' classification) and a still used equation that describes the adsorption of liquid mixtures by solids and allows to separate the contributions from the two components of the solution.
