摘要
研究了葡萄糖存在下TiO2光催化还原Cr(Ⅵ)过程中葡萄糖浓度、Cr(Ⅵ)初始浓度及不同反应条件对Cr(Ⅵ)光降解速率的影响.TiO2催化剂悬浮体系能有效地光催化还原溶液中Cr(Ⅵ)离子;葡萄糖的存在对TiO2的光催化还原Cr(Ⅵ)的反应具有明显的促进作用,符合一级反应动力学规律.
The effects of different initial Cr()concentration and grape sugar concentration and different conditions of reaction on photoreduction rate of Cr() in TiO_2 dispersion have been investigated. Photocatalytic reduction of Cr() in TiO_2 dispersion is in accord with stair kinetic equation. The grape sugar exhibits promotion effect on Cr() reduction.
