| Resumo(s): | Four model dyes were synthesised using classical preparative techniques. They represent the molecular structures frequently used in the production of industrial textile mordant dyes. Dyes decolourisation was developed in a lab-scale thin film photoreactor equipped with a white lamp and quartz tube, in the presence of different semiconductors, such as TiO2, ZnO and Fe2O3. The quantum yields of photochemical degradation were determined. The contribution of this photocatalytic process to the textile wastewater decolourisation will be discussed. |
