A photochemical UVC/H<sub>2</sub>O<sub>2</sub> oxidation system was applied for the decolourisation of two real textile wastewaters collected after biological from different wastewater treatment plants.
This work evaluates the photocatalytic reduction of Cr(VI) to Cr(III)using different catalysts: titanium-based and kaolin-based materials. The assays wereconducted in presence citric acid/tartaric acid as hole/HO• scavenger, using atubular photoreactor irradiated by UVA light. reaction rate thepresence titanium nanosheets with pozzolan (TNS-PZ) showed a ten-fold increasewhen compared commercial TiO2-P25 nanoparticles. effect catalystloading on was evaluated TNT-PZ. Then, at optimumcatalyst...
Hazardous waste from the hot rolling metal process may have a different and alternative final destination by becoming photocatalyst for wastewater treatment. The photocatalytic potential of mill scale (MS) steel plant was evaluated hexavalent chromium reduction synthetic real matrices under slurry conditions (MS particles dispersed in solution) or immobilized Raschig rings. Experiments were conducted an annular photoreactor irradiated UVA light. rings coated with MS electrostatic link PEGMA...
