Abstract
In order to realize the proper treatment of wastewater containing azo dyes, a silica-base supported BaF,2,-nano-TiO,2, composite (hereinafter called the composite) was prepared by a three-step synthetic procedure and utilized for the decolorization and degradation of orange Ⅱ in aqueous solution. It was found that the irradiation time and solution pH value was important parameter that ensured the degradation effect of γ-rays at low dose. The optimal doping ratio of BaF,2, to nano-TiO,2, was determined to be 1:1 (,m,BaF,2,:,m,TiO,2,). Furthermore, it was found that a highly reductive atmosphere (N,2,) favored the formation of hydroxyl radicals (·OH), which were responsible for the efficient degradation and mineralization of orange Ⅱ. The decolorization rate of the orange Ⅱ, Reactive black 5 and Reactive blue 222 dyes solution by the radiocatalysis system was 96.8%, 95.3% and 99.9%, respectively; and total organic carbon (TOC) removal rate of the orange Ⅱ, Reactive black 5 and Reactive blue 222 dyes solution achieved 92.5%, 40.2% and 98.6%, respectively. Thus, it was shown that the composite could be applied to the treatment of wastewater containing azo dye mixtures. The results of this study extend the technical applications of the TiO,2, photocatalytic oxidation technology.
