Abstract

Some of our studies were devoted to characterise acid-base properties of some solid substrates like oxides : MgO, ZnO, SiO2 and Al2O3, carbon fibres and polymers as PMMA at various tacticities adsorbed on silica and on alumina by using inverse gas chromatography(IGC) at infinite dilution, systems, that are known to interact strongly through acid-base interactions and ionic bonds. In this paper, we used IGC technique to characterise three textile materials (in glass fibres), noted respectively A, B and C. To do this, we used our model previously elaborated and giving the specific enthalpy of adsorption (-DeltaH(sp)) of a polar molecule adsorbed on a solid : (-DeltaH(sp)) = K-A.DN + K-D.AN - K. AN.DN, were DN and AN are the electron donor and acceptor numbers of the molecule and K-A. and K-D are the acidic and basic constants of the solid. The parameter K reflects the amphoteric character of the solid. Values of K-A, K-D, and K were obtained from this model by using Mathematica program, and allowed to give the following conclusions:

Material A has an acidic character and it is more acidic than the two other materials.

Material B has an amphoteric character with a basic tendency.

Fibre C is the more basic material relatively to the others, the ratio between its basic constant to acidic constant being close to 3.
