Abstract
Ozone is a strong oxidizing agent and in O3 alkenes presence, initiates a cleavage reaction called ozonolysis. In this chemical reaction multiple C-C bonds are replaced by double bonds with oxygen (oxidation). Ozone can significantly reduce the testing time in oxidation measurements. Although there are several commercial devices employed to produce the ozone as well as to measure its concentration, ozone controlled generation is still a challenge. This paper describes the development of a device capable of supply a controlled ozone atmosphere to be employed during oxidation tests. The device is composed of an ozone generator Corona type, an absorption cell to measure ozone concentration along with two systems used for signal conditioning and data acquisition. The proposed ozone detector uses visible light absorption trough an LED, as the light source, along with a photodiode, as a photodetector.
