Models of adsorption kinetics on rough surfaces

This article analyzes adsorption kinetics of fractal interfaces and sorption properties of bulk fractal structures. An approximate model for transfer across fractal interfaces is developed. The model is based on a constitutive equation of Riemann-Liouville type. The sorption properties of interfaces and bulk fractals are analyzed within a general theoretical framework. New simulation results are presented on infinitely ramified structures. Some open problems in the theory of reaction kinetics on fractal structures in the presence of nonuniform rate coefficients (induced e.g. by the presence of a nonuniform distribution of reacting centres) are discussed.
