  • Chlorine dioxide (OClO) is an important indicator for Cl-activation. The monitoring of OClO appears to be crucial for understanding the chemistry of Cl-initialed oxidation and its impact on air quality in polluted coastal regions and industrialized areas. We reportthe development of a Xe arc lamp based near-ultraviolet (335-375 nm) incoherent broad-band cavity enhanced absorption spectroscopy (IBBCEAS) spectrometer for quantitative assessment of OClO in an atmospheric simulation chamber. The important intermediate compound CH2O, and other key atmospheric trace species (NO2) were also simultaneously measured. The instrumental performance shows a strong potential of this kind of IBBCEAS instrument for field and laboratory studies of atmospheric halogen chemistry.

Near-ultraviolet Incoherent Broadband Cavity Enhanced Absorption Spectroscopy for OClO and CH2O in Cl-initiated Photooxidation Experiment (cited: 3)

Abstract: Chlorine dioxide (OClO) is an important indicator for Cl-activation. The monitoring of OClO appears to be crucial for understanding the chemistry of Cl-initialed oxidation and its impact on air quality in polluted coastal regions and industrialized areas. We reportthe development of a Xe arc lamp based near-ultraviolet (335-375 nm) incoherent broad-band cavity enhanced absorption spectroscopy (IBBCEAS) spectrometer for quantitative assessment of OClO in an atmospheric simulation chamber. The important intermediate compound CH2O, and other key atmospheric trace species (NO2) were also simultaneously measured. The instrumental performance shows a strong potential of this kind of IBBCEAS instrument for field and laboratory studies of atmospheric halogen chemistry.
