Title: Photoionization Efficiencies of Five Polycyclic Aromatic Hydrocarbons

Abstract

We have measured photoionization-efficiency curves for pyrene, fluoranthene, chrysene, perylene, and coronene in the photon energy range of 7.5-10.2 eV and derived their photoionization cross-section curves in this energy range. All measurements were performed using tunable vacuum ultraviolet (VUV) radiation generated at the Advanced Light Source synchrotron at Lawrence Berkeley National Laboratory. The VUV radiation was used for photoionization, and detection was performed using a time-of-flight mass spectrometer. We measured the photoionization efficiency of 2,5-dimethylfuran simultaneously with those of pyrene, fluoranthene, chrysene, perylene, and coronene to obtain references of the photon flux during each measurement from the known photoionization cross-section curve of 2,5- dimethylfuran.

  • Three certified reference materials, polychlorinated biphenyls (PCBs) from river sediment, polycyclic aromatic hydrocarbons (PAHs) from urban air particulate matter, and PAHs from highly contaminated soil, were extracted with pure CO[sub 2] at conventional (50[degrees]C) and high (200[degrees]C) temperatures. At 50[degrees]C, raising the extraction pressure (350--650 atm) had no effect on extraction efficiencies from any of the samples. High recoveries were obtained in 40 min from the highly contaminated soil regardless of temperature. However, PCBs from sediment and the PAHs from air particulates were efficiently extracted only if the temperature was raised to 200[degrees]C. At 200[degrees]C, PCBs were effectively extracted atmore » any pressure (150--650 atm), while both higher temperature and pressure increased the recovery of PAHs from air particulates. These results demonstrate that temperature is more important than pressure for achieving high extraction efficiencies when the interactions between pollutant molecules and sample matrices are strong and indicate that increasing SFE temperatures may be a useful alternative to adding organic modifiers for achieving high extraction efficiencies from environmental samples. 32 refs., 4 figs., 3 tabs.« less
  • The objective of this report was to (a) determine if charge-transfer reactions occurred in IMS (ion mobility spectrometry), (b) explore trends in charge-transfer selectivity in binary mixtures of aromatic hydrocarbons, (c) quantify behavior of photoionization-IMS response curves, and (d) compare these events to CI (chemical ionization) selectivity of the same compounds. Aromatic hydrocarbons were chosen for convenient comparison of results with prior findings in PI-IMS.
  • A common reaction pathway involving ion-molecule reactions of excited ions in indicated for a series of polycyclic aromatic hydrocarbons photoionized using intense pulsed excimer lasers (248 and 308 nm). The overall yields of free electrons and free aromatic radical cations created by two-photon ionization are measured by laser flash photolysis in cyclohexane and in 2-propanel solutions. The electron yields increase with increasing photon energies and photon flux, but the yield of radical cation is found to decrease with increasing photon flux. Photoproducts derived from aryl and solvent radicals are observed and quantified by GC and GC-MS, and their yields increasemore » with increasing photon energy and photon flux. The diminished yield of radical ions at higher photon flux suggests an alternate higher energy reaction pathway for the radical cation. While aryl radical cations are relatively unreactive, an excited aryl radical cation could protonate the surrounding solvent, leading to aryl radical formation (AH[sup [center dot]+*] + RH [yields] A[sup [center dot]] + RH[sub 2][sup +]). Solvent radical formation would then result from hydrogen atom abstraction by aryl radicals. Product studies support this ion-molecule reaction pathway and exclude alternate mechanisms involving neutral excited state homolysis. 22 refs., 13 figs., 4 tabs.« less
  • Polycyclic aromatic hydrocarbons (PAHs) play important roles in the formation of soot from combustion. The PAHs are formed from incomplete combustion, and are thought to pose a particularly great risk to health. Isomeric identification of PAHs is a big challenge. In this article, we describe an apparatus that combines tunable synchrotron vacuum ultraviolet (VUV) photoionization with molecular-beam mass spectrometry for identifying isomers of PAHs formed in combustion. The isomers of PAHs can be distinguished with measurements of photoionization mass spectrometry and photoionization efficiency spectra. With its unique features, the apparatus provides superior mass and energy resolution and is potentially amore » powerful tool for the study of formation mechanisms of PAHs and soot in combustion.« less
  • A new high temperature transfer line, membrane inlet probe (HTTL-MIP) coupled to a photoionization detector (PID) and gas chromatograph/mass spectrometer (GC/MS) was used to rapidly profile and speciate polycyclic aromatic hydrocarbons (PAH) in the subsurface. PID signals were in agreement with GC/MS results. Correlation coefficients of 0.92 and 0.99 were obtained for discrete and composite samples collected from the same exact location. Continuous probe advancement with PID detection found coal tar, a dense nonaqueous phase liquid, in soil channels and saturated media. When samples were collected conventionally, split, solvent extracted, and analyzed in the field and confirmation laboratory, GC/MS measurementmore » precision and accuracy were indistinguishable; despite the fact the field laboratory produced data five times faster than the laboratory using standard EPA methods. No false positive/negatives were found. Based on these findings, increased confidence in site conceptual models should be obtained, since PID response indicated total PAH presence/absence in 'real-time', while GC/MS provided information as to which PAH was present and at what concentration. Incorporation of this tool into a dynamic workplan will provide more data at less cost enabling environmental scientists, engineers, and regulators to better understand coal tar migration and its impact on human health and the environment. 24 refs., 3 figs., 4 tabs.« less
