heal.abstract	In this work, in order to describe the impact of ozone on ferric oxide - a common constituent of building materials - in purely scientific terms, a novel methodology that of Reversed Flow-Inverse Gas Chromatography (RF-IGC or RF-GC) is proposed. Five important physicochemical quantities concerning adsorption of ozone on the solid surface of ferric oxide are determined, in five temperatures, in a time-resolved way. By means of a simple PC-program, the values of local adsorption energy, local adsorption isotherm, local monolayer capacity, probability density function for adsorption energy, and energy from lateral interactions are calculated. Thus, the role of surface heterogeneity, lateral interactions and different distributions of active sites (surface topography) on the adsorption of ozone on the surface of ferric oxide is analyzed in the way the RF-IGC method has it developed. © Taylor & Francis Group, LLC.	en
