Chemical oxygen demand analysis using ozone oxidation
Developed mainly for indoor analysis, conventional analysis for water pollution, such as COD and TOD, are not suitable for on-line measurement. Actually, commerical water quality autoanalyzers which automate these conventional methods have major disadvantages: they often require frequent maintenance and they have a high operating cost due to the large amount of chemicals consumed. We have studied the use of ozone as a new method applicable to on-line water pollution monitoring. As is well known, ozone is a powerful oxidant that can oxidize most organic pollutants in water. Therefore, if the amount of oxygen consumed in the ozone oxidation can be measured, we may use this quantity as an index of water pollution.
