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.

In this paper the photocatalytic activity of TiO2-PANi nanocomposites prepared using two differentIn-situpolymerization methods have been investigated. The same pressure, temperature, precursors, mole ratio, and solvent have been employed for preparation of nanocomposites. The synthesized nanocomposites were characterized by FESEM, XRD and FTIR. Results revealed the successful preparation of TiO2- PANI nanocomposites. TiO2-PANi nanocomposite synthesized using method 2 showed very well dispersed TiO2nanoparticles on the surface of PANi. There is no agglomeration of TiO2nanoparticles in PANi matrix. The photocatalytic activities of nanocomposites were evaluated by using photo degradation of Methylene Blue (MB) in aqueous solution under UV irradiation. These nanocomposites exhibit much higher photocatalytic activity compared with TiO2.
