The Dubinin–Radushkevich–Kaganer equation
Abstract
The Dubinin–Radushkevich–Kaganer (DRK) model is discussed in general in terms of the replacement of Polanyi's concept of an adsorption space by a bidimensional concept that leads to a relation between that model and the adsorptive energy distribution. Since the model assumes a Rayleigh distribution, it is found that the usual criteria of the experimentalists, such as the adaptation of the DRK equation to the experimental data, are not sufficient. These general ideas are illustrated with simulations of some representative cases of actual laboratory situations.
