Název v původním jazyce

Pressurised solvent extraction of nitrated derivatives of polycyclic aromatic hydrocarbons from roadside dust

Popis výsledku v původním jazyce

An analytical method based upon the pressurised solvent extraction and gas chromatography and mass spectrometry (GC-MS) for analysis of nitrated derivatives of polycyclic aromatic hydrocarbons (nitro-PAHs) in roadside dust has been developed. Five nitro-PAHs (1-nitronaphthalene, 1-nitropyrene, 9-nitroanthracene, 2-nitrofluorene, 6-nitrochrysene) were chosen for this study because of their variable physical properties and effect on human health. Experiments with spiked inert matrix were used for the bestextraction conditions finding. Different extraction conditions (temperature, pressure, solvents and duration of extraction cycle) were examined. The highest recoveries were observed at the extraction pressure of 14 MPa, temperature of 100C and two cycles of 5 min extraction time, when dichloromethane was used as an extraction solvent. These conditions were applied to the extraction of nitro- PAHs from roadside dust. After extraction the nitro-PAHs fraction was isolated by the silica gel
