history of chemistry

Abstract

This work completes the historical presentation of the theory proposed in 1922 by Wolfgang Ostwald and Ramón de Izaguirre for adsorption from solution. After examining biographic data for one of the authors following the formulation of the theory, the impact of the latter is examined either as a whole or through a classification of adsorption isotherms or an equation that describes adsorption of mixtures of miscible liquids by solids.
