New Mesoporous Aluminosilicates Used for Solid-phase Extraction of Hydrocarbons and Fragrance Compounds

ABSTRACT

The extraction efficiency of three newly synthesized mesoporous aluminosilicate materials with different Si/Al ratios was evaluated. The surface morphology and pore sizes of new mesoporous materials were determined, and the adsorption properties were examined. Scanning electron microscopy–energy dispersive spectroscopy was used to characterize the Al content in the material. The Brunauer, Emmett, Teller Isotherm method was used for determining the surface area and the pore size of synthesized materials. The adsorption properties of examined materials were evaluated by solid-phase extraction in classical form and using microsolid-phase extraction. In addition, the use of the examined aluminosilicates was investigated as sorbents for hydrocarbons and fragrance compounds.
