Abstract

An Na₄EDTA-assisted pressurized liquid extraction (PLE)/ one-step cleanup system was developed for the routine analysis of polycyclic aromatic hydrocarbons (PAHs) in sediments. The aim of the work was to reduce the amount of solvents used and the manual handling time for each sample while improving recovery. The average recovery levels of PAHs were enhanced about 4% with the addition of Na₄EDTA as modifier than without Na ₄EDTA for the standard PLE system. Although the average recoveries decreased (3-5%) compared to the Na₄EDTA-assisted standard PLE extraction system, the Na₄EDTA-assisted PLE/one-step cleanup system gave a reasonable high extraction efficiency. It could be coupled to GC/MS directly without further cleanup process.
