New equations and models on two-dimensional state of solid surfaces were previously elaborated in many other studies. Results obtained were used in this paper to determine and quantify physicochemical properties of some solid surfaces, and especially, to study the acid-base superficial characteristics of solid substrates like oxides, carbon fibers, textiles, etc. The technique used was the inverse gas chromatography (CGI) at infinite dilution. The acid-base constants were calculated for many solid surfaces: MgO, ZnO, textile materials and carbon fibers.
Key words: Oxides, acid-base constants, inverse gas chromatography.
