Photocatalytic ozonation of dimethyl phthalate over TiO2 prepared by a hydrothermal method

摘要：

TiO2 catalyst was prepared by two kinds of different methods. The photocatalytic activity of TiO2 prepared by the hydrothermal method is 2.5 times higher than that by sol-gel in degradation dimethyl phthalate (DMP). The combined photocatalysis with UV irradiation and ozonation (TiO2/UV/O3) process considerably improved mineralization and degradation of dibutyl phthalate compared to combined photocatalysis with UV irradiation (TiO2/UV) process, combined ozonation with UV irradiation (UV/O3) process and ozonation alone (O3) process. DMP can be quickly mineralized in TiO2/UV/O3, its mineralization process followed Langmuir-Hinshelwood model. Its rate constant k is 0.42 mg/(L·min) and Langmuir adsorption coefficient K is 0.0417 L/mg.
