dcterms:description
Two modern extraction techniques - the focused microwave-assisted extraction (FMAE) and the accelerated solvent extraction (ASE) - were compared to a classic ultrasonic extraction. Different groups of environmental pollutants were used as model compounds: acrylamide and some representatives of persistent organic pollutants (POPs) including polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs), and polychlorinated biphenyls (PCBs). The methods were applied both to some spiked samples of soils and to selected certified reference materials (sewage sludge, freshwater harbour sediment, etc.) for a quality assurance. Quantification of the target compounds was performed by either HPLC (for acrylamide and PAHs) or by GC/ECD (for organochlorines). The results demonstrated that these new and more sophisticated extraction techniques are comparable to conventional methods as for the compound recoveries; however, they are less time- and solvent-consuming. In general, the ASE technique showed to Cílem práce bylo zhodnocení moderních extrakčních technik, které jsou vhodné ke stanovení polymerů a xenobiotik.
