Determination of phenanthrene and fluorene by MCM-41-dispersive micro-solid phase extraction combined with gas chromatography-mass spectrometry
A simple and rapid technique termed MCM-41-dispersive micro-solid phase extraction (MCM-41-D-μ-SPE) combined with gas chromatography-mass spectrometry (GC-MS) was utilized for the analysis of polycyclic aromatic hydrocarbons (PAHs) in water samples. Fluorene and phenanthrene were selected as model c...
