APPLICATION DE LA PHOTOCATALYSE POUR LA DEGRADATION DE LA POLLUTION AZOTES

Abstract

Nitrogen exists in nature either naturally or due to the flowing effluents of industry and can have a direct influence on living organisms and the environment. Therefore, these effluents must be treated before being discarded. Among the treatment processes for these effluents, we cite the Advanced Oxidation Processes, of which the heterogeneous photo catalysis process is the most suitable to apply in our laboratory. This work of memory is the subject of a kinetic study of the degradation of this pollutant with the heterogeneous photo catalysis process. In this study, several parameters were studied, namely the concentration of TiO2 as well as that of nitrogen, the pH of the medium, etc. the pH has no significant influence on the speed and the yield of the photo catalytic degradation reaction. The kinetic study has shown that the degradation reaction of the pollutant is pseudo-first order.
