Κατασκευή φωτοαντιδραστήρα (UV) για περιβαλλοντικές εφαρμογές

Abstract

Pollution of surface waters as well as that of underground waters consist a significant problem for the ecosystem and the society at large. The aim of the present study is the construction and experimental study of a light water reactor in linear radiating arrangement UVC 254nm for the purification of surface and underground waters, as well as wastewaters. The light water reactor constructed based on Bolton and Linden (2003) protocol.When we exposed KI to monochromatic radiation UVC 254nm converted into I3, which adopting the intensity of the UVC radiation in relation to the distance from the lamps. The conclusion is that as far is the reagent from the source, the more little energy receives. Subsequently, carried out photolysis on creatine and creatinine for observation decomposition of xenobiotic substances. When we run the two substances together we observed absorption at 254nm, but we can’t recognize which substance is. The result was that the creatinine decomposed and creatine not. This is due to the fact that creatinine absorbs at wavelength 254nm and creatine not. The experiments were conducted in the laboratories of the Technological University of Cyprus in the department of Science and Environmental Technology. At the moment, the light water reactor belong to the AQUA laboratory as an important part of laboratory equipment. To conclude, the use of photolysis carried out decomposition of xenobiotic substances in the water. For decomposition the light water reactor should provide appropriate ventilation and temperature conditions.
