【摘要】 以染料橙黄Ⅱ和甲基橙为对象,采用对比实验的方法,研究了不同光源照射下 -环糊精( -CD)对光催化降解染料的脱色速率.结果表明:在紫外灯照射下,-CD的加入使TiO2对橙黄Ⅱ和甲基橙的光催化脱色速率分别降低51.35%和43.52%;在高压汞灯照射下,-CD的加入使TiO2对橙黄Ⅱ和甲基橙的光催化脱色速率分别提高22.3和70.4倍.更多还原

【Abstract】 Dye Orange II and Methyl Orange were used as objects to investigate the rates of TiO2 photocatalytic dye decolourization in the presence of -cyclodextrin ( -CD) under UV and high pressure mercury lamp illumination. The experiment results showed that decolourization rates of the dye by TiO2 were reduced by adding the -CD under UV irradiation. Decrease of decolour- ization rates of the Orange II and Methyl Orange were 51.35% and 43.52%. But increase of decol- ourization rates of the Orange II and Methyl Orange were 22.3 and 70.4 times by adding the -CD under high pressure mercury lamp illumination.更多还原
