Degradation of Low Concentration Benzyl Butyl Phthalate (μg•L^-1 range) in the Tail Water of Municipal Sewage Plant by UV/H₂O₂

Abstract:

The degradation of Benzyl butyl phthalate (BBP) at low concentration (μg•L^-1 range) by the direct UV irradiation, H₂O₂ oxidation and UV/H₂O₂ advance oxidation process was investigated in this study. The experiment results showed that the decomposition efficiency of UV or H₂O₂ was worse than that of UV/H₂O₂. Under the condition of 24.26μw•cm^-2 UV irradiation and 2.49 mM H₂O₂, the degradation efficiency of BBP at low concentration was over 90% after 30 min. In addition, the solution pH was found to have no significant effect on the photo-degradation of BBP. The degradation of low concentration BBP in the tail water of municipal sewage plant was 84.23% with UV/H₂O₂ at the UV irradiation (24.26μw•cm^-2) and H₂O₂ (2.49 mM) without adjusting pH.
