Ultrasound-assisted surfactant enhanced emulsification microextraction method coupled with gas chromatography-mass spectrometry for the determination of selected polycyclic aromatic hydrocarbons in aqueous samples

A simple and rapid microextraction method termed as ultrasound-assisted surfactant enhanced emulsification microextraction (UASEME) was developed for the determination of fluoranthene (FLU) and phenanthrene (PHE) in aqueous samples followed by gas chromatography-mass spectrometry (GC-MS). Six important parameters, that affect the extraction efficiency of polycyclic aromatic hydrocarbons (PAHs) were evaluated and the results were as follow
