Paper Abstract

Kinetics of oil water solutions photodegradation under action of narrow band irradiation of XeBr*-excilamp (λ~283 nm) and iodine lamp (λ~206 nm) is presented. Power of lamps reached 10 mW/cm2. In all experiments TiO2 (rutile) powder was used as a catalytic agent. Photocatalytic degradation kinetics was controlled by laser fluorescence spectrometer. The measuring complex was based on the pulse-repetitive Nd:YAG laser (266 nm) with Q-switching. Dependencies of fluorescence intensity on irradiation time were made using laser-induced fluorescence spectra. It has been found that at initial time of irradiation, the photodegradation rate in oil aqueous solutions was higher in the case of XeBr* lamp, however, after 20 minutes of irradiation, major photodegradation was observed in the both cases.
