Organosilicas were pre-pared in tetraethylorthosilicate–3-(chloropropyl)triethoxysilane–β-cyclodextrin–ethanol–water system. These materials were characterized by IR spectroscopy and thermogravimetric analysis. Porosity of orga-nosilicas was characterized on nitrogen adsorption/desorption isotherms. The porosity analysis demon-strates that cyclodextrin-silica based materials are an isotherm Type I substance. The surface areas of the organosilicas with incorporated β-cyclodextrin are in the range 430–580 m2 g1; materials containing up to 0.005 mmol g1of β-cyclodextrin moieties have been successfully prepared. Synthesized organosilicas are stable in aqueous medium and could be used in processes of pollutants removal. The present study demon-strates a simple time-saving method of cyclodextrin-containing silicas obtaining via one-pot synthesis in mild condition without using toxic solvents, costly templates or cyclodextrin derivatives.
