| heal.abstract | This paper deals with the application of the CPSM and alpha(s) methods to determine microporosities of silica gels and microporous clays pillared with Al1-xFexOy oxidic species. A reasonably good agreement between the two methods was ascertained. However, the CPSM method evaluates slightly higher relative microporosities in the case of pillared clays. By raising the Fe content a decrease of the relative microporosity of pillared clays was observed. The CPSM method is most appropriate for the tracing of supermicropores i.e. pore sizes D-p=1-2 nm, as it is based on the assumption that an adsorbed gas monolayer exists. The CPSM model through the simulation of gas sorption hysteresis, enables a unified analysis of porous materials exhibiting mixed meso-micropore structures, involving evaluation of meso-micro pore size distribution, determination of pore surface area in good agreement with the corresponding values from a Langmuir equivalent model, estimation of tortuosity factors tau(CPSM) and detection of relative microporosity in satisfactory agreement with relevant data obtained by the alpha(s) method. | en |
