Ozone Chemistry - NAS Home

In this fashion it is estimated that one molecule of chlorine can degrade over 100,000 molecules of ozone before it is removed from the stratosphere or becomes part of an inactive compound. These inactive compounds, for example ClONO2, are collectively called 'resevoirs'. They hold chlorine in an inactive form but can release an active chlorine when stuck by sunlight.

ozone decomposition - Lenntech

Ozone can be used in water treatment, for the reduction of the concentration of NOM. The concentration of NOM in natural waters can vary from 0,2 – 10 mg l-1 [6]. The influence of NOM on ozone is twofold. Dependent on the type of NOM, it can be oxidized directly by NOM. This is the case for compounds which easily react with ozone, such as double bonds, activated aromatic compounds ...
