英文摘要	The effects of additives (NH(4))(2)S(2)O(8), H(2)O, and surfactant sodium dodecyl benzene sulfonate (DBS) on the photocatalytic degradation of pigment brilliant red 6B in the presence of TiO(2) were studied. The pigment brilliant red 6B, TiO(2), additives and deionized water were added into a beaker. After stirred for 0.5 h with a magnetic stirrer in the dark, the mixture was irradiated with a high-pressure Hg lamp (100 W, lambda = 365 nm). The discoloration time of the mixture was used to evaluate the degradation of pigment brilliant red 6B, which was not dissolved completely in water without DBS. The concentration of pigment brilliant red 6B in the presence of DBS was determined with UV-Vis spectrophotometer because of the increased solubility. (NH(4))(2)S(2)O(8) accelerated remarkably the photocatalytic degradation of the water-insoluble pigment brilliant red 6B. The acidic medium was suitable for the degradation of pigment brilliant red 6B in the presence of (NH(4))(2)S(2)O(8). H(2)O(2) also enhanced the degradation rate of pigment brilliant red 6B. The reused numbers of TiO(2) were increased with the addition of H(2)O(2) and with the increase of temperature, and H(2)O(2) could be efficiently utilized. DBS decreased the degradation rate of pigment brilliant red 6B. The degradation of pigment brilliant red 6B in acidic and alkaline conditions was greater than that in neutral condition in the presence of DBS. On the contrary, the degradation rate of DBS was slightly greater in neutral condition. The co-degradation of pigment brilliant red 6B and DBS was measured.
