【摘要】采用溶胶—凝胶法在玻璃表面制得TiO2 (锐钛型 )薄膜 ,研究了以 2 5 4nm的紫外线为光源 ,酸性品红(AF)在TiO2 薄膜上的光催化降解初始速率与溶液初始浓度、初始pH值及外加氧化剂H2 O2 的关系 .结果表明 ,AF的光催化降解行为采用Langmuir Hinshelwood(L H)模型来解释 ,利用TiO2 薄膜作为光催化剂光降有机物AF具有较好的应用前景 .更多还原

【Abstract】 TiO 2(anatase) has been immobilized on glass using Sol gel processing.The photocatalytic degradation of Acid fuchsine(AF) was studied using one 254 nm UV lamp as light source.The initial reaction rates of AF under initial concentrations,initial pH values and additional oxidation were also investigated.The behavior of the photocatalytic degradation of Acid fuchsine may be explained by Langmuir Hinshelwood(L H) model.And the photocatalytic degradation of organic waster can be catalyzed by TiO 2 thin film with better useful prospect.更多还原
