| Abstract | The study deals with the validation of some assumptions regarding the existence
of excited ozone.
In the theoretical development, various possibilities have been checked by using the
concepts of thermodynamics and engineering leading to the conclusion that a mixture of various
levels of ozone is most probably generated in an ozonizer depending on the prevailing conditions
in it.
Theoretical consideration have been experimentally supported by generating ozone under
different conditions, i.e. high voltage with dilution and low voltage without dilution. Reactivity
of these ozones have been tested in various media and found to be in agreement with the
theoretical consideration
Ozonation of oxalic acid has been tried, resulting in the conclusion that the mechanism
of activation of ozone by UV in liquid phase could differ from those in gasous phase or ozone
in liquid phase reacts with species such as OH, these are the species excited by UV and not
directly by ozone.
The experiments also support previous investigations such as bleaching of ozone in acidic
media, underactivity of ozone with oxalic acid, and the reaction of oxalic acid with ozone in the
presence of UV. This study provides the most probable explanation for such. |
