Abstract
Microwave-assisted micellar extraction (MAME) has been tested for the recov ery of polycyclic aromatic hydrocarbons (PAHs) present in samples of marine sediments. An aqueous solution of the nonionic surfactant polyoxyethylene( (23))dodecyl ether (Brij 35) was employed as the extracting medium. The pro posed approach showed recovery efficiencies comparable to those afforded by the Soxhlet technique with organic solvents, but a neat reduction of the e xtraction times and a better reproducibility were observed. A MAME-based pr otocol was successfully applied for the analysis of a certified sample.
