Abstract

Chromatographical study of alkyl-glucosides adsorption at solid-liquid interface from aqueous
solutions were shown in this paper. The study of n-octyl-β-D-glucopyranoside and n-decyl-β-D-maltoside
adsorption has been carried out on the mesoporous ordering silica SBA-15 using frontal and circulation
chromatographical methods at 298 and 318 K.
As «proof of isotherms» a simple two-step adsorption model has been applied. The results of
modeling show the reasonable values of the equation constants. Base on the isotherm analysis we try to
figure out the conformation of surfactants species in pores. Thermodynamic parameters of surfactant
adsorption at solid-liquid interface have been determined.
