Abstract
The Monte Carlo simulation method is used to study the effects of nonu niformity on adsorption in slit-like pores. Three types of nonuniformi ty are considered: polydispersion of pore size diameters in the system , and geometrical as well as energetical heterogeneities of the pore w alls. The differences and similarities in the pore filling in differen t systems are discussed. It is demonstrated that from measurements of the adsorption-desorption isotherms it is very difficult, if at all po ssible, to say anything about the origin of nonuniformity effects. On the other hand, the shape of the adsorption isotherms is, to some exte nt, sensitive to the distribution of nonuniformities in the system. (C ) 1997 Elsevier Science S.A.
