Identification of Major Water-Soluble Fluorescent Components of Some Petrochemicals

摘要

The chemical identities of several organiccompounds that dominate the ultraviolet (UV) fluorescence of water after exposure to gasoline, diesel fuel and crude oil are pre- sented. A combination of high-performance liquid chro- matography with UV-fluorescence detection, fluorescence spectroscopy and gas chromatography-mass spectrometry (GC-MS) is used to show that naphthalene, methyl- naphthalene and methylstyrene are the major fluorescent specie sin water following exposure to gasoline. These compounds are not dominant in water exposed to other petrochemicals we studied.
