OBJECTIVE: To establish a method for analysis of polycyclic aromatic hydrocarbons( PAHs) in water by solid extraction column with GC-MS/MS.
METHODS: The extraction effects of columns, such as Oasis HLB, C_(18), Oasis MCX and Oasis MAX, were compared. The influence of different kinds of solid phase extraction columns for the PAHs and method ology study were investigated. The samples were extracted by preactivated C_(18) column, eluted by dichloromethane, detected by gas chromatography-triple quadrupole mass spectrometry.
RESULTS: Under the established optimal test condition, the recoveries of PAHs were 78%-130%, the RSD were 0. 8%-5. 0%, the limit of quantitation were in the range of 0. 0007-0. 0199 μg/L.
CONCLUSION: The method is fast and easy, it can meet the requirement for analytical measurement of various PAHs in water.
