The Chemical Reactions of Ozone and Their Role in Developing Improved Analytical Methods

Abstract
Most methods for the determination of ozone have been developed by utilizing, with or without odifications, existing methods for chlorine determination. The problem with this approach is that ozone chemistry is very different from chlorine chemistry. We believe that a detailed understanding of the mechanism of ozone decomposition and the chemistry of the by-products is essential in order to develop selective methods forozone. This paper briefly describes the ozone decomposition mechanism and introduces the concept of an “Ideal Method. The indigo method is examined as an “Ideal method” and the automation of this method by Flow Injection is discussed.
