| Abstract | Experiments were performed to investigate the effects of sulfur dioxide (0–10 ppm) and chlorine (0–15 ppm) on ozone and nitric oxide concentrations in irradiated mixtures of nitrogen dioxide (1–5 ppm) and air. The mixtures were irradiated by ultraviolet fluorescent lamps while flowing at a steady speed through a 9m long, 15.2cm i.d. Pyrex tube. The presence of sulfur dioxide produced no measurable change in the ozone and nitric oxide concentrations. The addition of small quantities of chlorine increased the ozone concentration in much the same manner as the addition of a hydrocarbon. A reaction model was developed for the chlorine-nitrogen dioxide-air mixtures. The observed increase in ozone concentration could only be predicted if the following two reactions were included : ClOO + NO → NO2 + ClO and ClOO + NO → ClNO + O2. Significant quantities of unexpected condensation nuclei were also observed in the chlorine-nitrogen dioxide-air mixtures. |
