Microwave assisted extraction of polycyclic aromatic hydrocarbons from atmospheric particulate samples.

摘要: For several years, microwave assisted extraction (MAE) was applied to extract organic compounds such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls, etc., from soils, sediments and standard reference materials. Very few authors this methodology for the of PAHs atmospheric particulate matter. In present study, MAE with hexane/acetone (1 : 1) real samples investigated effect energy irradiation time studied. The yields extracted obtained by were compared those using traditional Soxhlet extraction. evaluated spiked two Analytical determinations carried out high performance liquid chromatography (HPLC) ultraviolet fluorescence detection. best recoveries achieved a 400 W an 20 min.
