Extraction of polycyclic aromatic nitrogen heterocycles from spiked soil samples

Original language description

Extraction recovery of ten selected polycyclic aromatic nitrogen heterocycles (PANHs), quinoline, 2-methylquinoline, 6-methylquinoline, 8-methylquinoline, acridine, benzo[h]quinoline, phenantridine, indole, 2-methylindole and carbazole from spiked soil samples was tested. Four different extraction techniques, pressurised solvent extraction (PSE), supercritical fluid extraction (SFE), Soxhlet warm extraction (SOXW) and standard Soxhlet extraction (SOX) were applied and compared. RP-HPLC technique with silica-based octadecyl stationary phase was used for recovery determination of individual PANHs. Supercritical fluid extraction has been found the most effective method for the extraction of selected PANHs from soil. Pressurised solvent extraction and Soxhlet warm extraction methods offered similar results with slightly lower extraction recoveries compared to SFE. On the contrary, standard Soxhlet extraction as a time consuming method with the low recovery of target analytes did not prove
