Textile and other dye house effluents from different industries have many worst effects on aquatic as well as non-aquatic life. The present work was carried out for the conditions optimization of degradation of Allura Red AC dye. This was done by UV treatment and examining the effects of different parameters on degradation i.e. pH, concentration of the dye, temperature, radiation exposure time and concentration of TiO₂. The efficiency of the treatment was monitored by checking the highest degradation value, parameters of water quality such as chemical oxygen demand (COD), biological oxygen demand (BOD) and toxicity. The end products of degradation of dye were checked out by UV/visible spectrophotometer, Fourier transform- infra red (FT-IR) and gas chromatographymass spectrometry (GC-MS) techniques. From the results, it was concluded that the degradation efficiency was in the order UV/H₂O₂/TiO₂> UV/H₂O₂> UV alone. Furthermore, it was also concluded that UV/H₂O₂/TiO₂ could be implemented on industrial scale for the removal of the toxic pollutants from industrial effluents.
