Original Abstract

In this contribution the study of O2 and O3 reactions with electrode surface in an ozonizer is presented. The electrode surfaces in ozonizer were treated in the discharge with pure (99.9999%) oxygen for long time. Then the discharge was switched off and pure oxygen or oxygen with ozone reacted with treated electrodes for different time periods. Then the ozone concentration at the ozonizer output was measured by the absorption spectroscopy. It was found that the molecular oxygen reacts with oxygen atoms adsorbed on electrode surfaces producing ozone. On the other hand the ozone concentration in switched off ozonizer stays constant for long time.
