PAH Extraction from Water Samples

Article

Researchers from IWW Water Centre (Mülheim an der Ruhr, Germany) and University Duisburg-Essen (Duisberg, Germany) developed a solid-phase extraction (SPE) procedure using extraction disks in the analysis of polycyclic aromatic hydrocarbons (PAHs) in surface water samples.

Researchers from IWW Water Centre (Mülheim an der Ruhr, Germany) and University Duisburg-Essen (Duisberg, Germany) developed a solid-phase extraction (SPE) procedure using extraction disks in the analysis of polycyclic aromatic hydrocarbons (PAHs) in surface water samples. The one-step extraction was followed by gas chromatography–mass spectrometry (GC–MS) analysis. They compared their results with those obtained using liquid–liquid extraction (LLE) and found that the SPE disk method provided much higher recoveries and better precision than the LLE method.
