Computerized continuous monitoring and analysis of ozone in solution

Abstract

This paper presents a method for continuous monitoring of ozone in water by using the Indigo colorimetric technique. The details of an instrument developed and used for this purpose are explained. Data obtained using the continuous ozone reading equipment in monitoring the ozone levels are presented. The instrument also can be used to measure the decay of ozone in ozonated waters, continuously giving a very accurate measure of ozone decay coefficients.
