Determination of Aromatic Compounds in Water by Solid Phase Microextraction and Ultraviolet Absorption Spectroscopy. 2. Application to Fuel Aromatics

摘要

Solid phase microextraction is coupled with ultraviolet absorption spectroscopy to determine fuel aromatic hy- drocarbons from unleaded gasoline, jet fuel(JP4), and no.1 diesel fuel in water. A rectangular"chip" of poly- (dimethylsiloxane)(OV-1) was used as the sorbent me- dium to selectively partition the various fuels from real water matrices without interferences from naturally oc- curring organics(e.g., humic and fulvic acids).
