摘要：

This study implicates the degradation of pigment red 238 (PR238) from aqueous solution employing photocatalytic processes. The procedure was carried out under UV radiation, SnO2 and H2O2 as well as Fenton process. The influence of process variables viz., pigment concentration (50-150 ppm), amount of catalyst (0.1-0.3 g/L), H2O2 concentration (0.3-0.9 mL), UV irradiation time (30-60 min) and pH (3-9) were studied for the removal of PR238. The experiments were conducted by exposing aqueous solutions of PR238 having photocatalyst with UV light and effect of process variables such as pH, concentration of pigment, concentration of H2O2 and amount of catalyst was investigated. The degradation of > 90% was achieved with Fenton process, whereas H2O2/UV and UV/H2O2/SnO2 furnished up to 78% and 89.6% PR238 removal, respectively. From results, it was concluded that the Fenton process is highly efficient for the removal of PR238, which can be employed for the removal of dyes form effluents
