The effect of CCl2F2 on ozone generation from oxygen

The production of ozone by negative corona discharge from O₂ + CCl₂F₂ (CFC12) mixtures is experimentally investigated at two pressures of gaseous mixture of 800 and 900 mbar in the CCl₂F₂ concentration range of (0–7)%. The efficiency of ozone generation is remarkably reduced with increasing content of CCl₂F₂ in the mixture with oxygen. The effect is more apparent at lower pressure of gaseous mixture. In order to identify the most likely process responsible for the inhibition of ozone production a discussion of the chemical kinetics of various processes is presented. This research was carried out with financial support from the Slovak Grant Agency for the project under the No. 1/5184/98 and the Action Austria-Slovakia project under the number 25s19.
