Abstract
In this present study the extraction of polycyclic aromatic hydrocarbons (P AHs) from marine sediments with a micellar medium of Polyoxyethylene 10 lau ryl ether by an ultrasound-assisted method has been studied. Factorial desi gn experiments were used in order to optimize the extraction parameters: ex traction time, surfactant concentration and surfactant volume:amount of sed iment relationship. The results suggest that surfactant concentration is st atistically the most significant factor. The analysis of extracts has been carried out by HPLC with UV detection. Fortified sediments gave an average recovery between 86.7 and 106.6%, with relative standard deviation of 2.02- 6.8% for PAHs with a ring number higher than three. (C) 2001 Elsevier Scien ce B.V.
