摘要
二氧化钛（ＴｉＯ２）膜光催化氧化法处理水中腐殖酸（ＨＡ）技术避免了以往悬浮相光催化时催化剂难以分离回收等回题，具有良好的应用前景．研究了光源种类、ＴｉＯ２膜的表面修饰和ＨＡ水溶液的ｐＨ值等因素对ＨＡ光催化氧化效率的影响，讨论了有关的机理并合理解释了实验现象．
The photocatalytic oxidation of humic acid(HA) in aqueous solution using TiO 2 film as a catalyst was studied in compared to a dispersion system, in which the suspended TiO 2 particles were difficult to be separated and recovered. The method showed a good application perspective. The effects of the photosources, surface modifications of TiO 2 film and pH value of HA aqueous solution on photocatalytic oxidation efficiencies were investigated. The involved mechanism were discussed.
