Abstract
In the present study, titanium dioxide (TiO2 ) nano-photocatalyst was characterized and used for the removal of estrone (E1) and estriol (E3), which are endocrine disrupting compounds (EDCs). The photocatalytic process is a very interesting alternative for the removal of such EDCs that is identified on the watch list of EU Decision 2015/495. The effects of operating parameters such as pH (3–10), contact time (1–10 min) and catalyst dose (0.025–0.100 g) were investigated. It was revealed that nano-TiO2 exhibited a significantly enhanced photocatalytic efficiency toward E1 and E3 degradation. The increased efficiency was attributed to increased catalyst dosage, decreased pH value and smaller catalyst size. In general, it was observed that the presence of TiO2 enhanced the photodegradation of E1 and E3; and that the particle size of TiO2 was an important factor influencing dye removal. In the kinetic study, our study is fitted by Langmuir–Hinshelwood model. In addition, the humic acid and co-existing anion concentrations were also investigated.
