Abstract
An experimental study on the nascent product of the OH heterogeneous reaction with NaCl was performed under dryand wet conditions using a bead-filled flow tube system coupled to a high-pressure chemical ionization mass spectrometer. Theozone concentration in the flow tube for the atomic hydrogen removal was varied in order to control the conversion reaction ofmolecular chlorine into HCl for the identification of the nascent product. The mass spectrometric observation was that the O3introduction reduced the concentration HCl, while it increased the concentration of Cl2 and ClO. Based on the experimentalresults, we suggest that the nascent product of the titled reaction is gaseous Cl2, which is followed by fast conversion into HCl inpresence of H. No significant difference in the concentration profile between under dry and wet (RH = 2%) conditions wasobserved.
