An efficient catalytic process for the treatment of genotoxic aniline wastewater using a new granular activated carbon-supported titanium dioxide composite

摘要: Abstract This work presents an efficient catalytic ozonation process for the treatment of aniline wastewater as a model pollutant. The uses granular activated carbon-supported titanium dioxide catalyst with environmentally-friendly and sustainable characteristics. Titanium composites were prepared by precipitation alcoholic tetrachloride solutions on two different carbon supports: Norit® GAC 1240 Plus ROX 0.8. method is improvement other composite preparation methods such hydrothermal impregnation immersion techniques, which also carried out comparison. It characterised our Brunauer–Emmett–Teller analysis, scanning electron microscopy-energy dispersive X-ray spectroscopy Fourier-transform infrared to assess influence support. Composites synthesised via this novel presented 25% increase in their initial specific surface area 9.1% loading. compared activity solutions, studied optimal pH ozone dose. Plus-supported gave highest removal yield 80.24% mineralisation total organic 45 min. With respect costs associated treatment, achieved 26.8 mg ozone/mg carbon.
