Hydrogen Peroxide and Ultraviolet-Visible Irradiation for the Oxidation of Organic Environmental Contaminants 过氧化氢和紫外-可见光辐射氧化有机环境污染物
发布日期: 1990-01-01
本文讨论了利用过氧化氢/可见-紫外辐射(H2O2/Vis-UV)去除水中有机物的方法。讨论了化学机理,包括光化学和光吸附、量子产率、紫外线照射和过氧化氢分解。与单独使用过氧化氢的氧化速率相比,该过程导致所有研究化合物的氧化速率显著增加。该工艺是一种成功的渗滤液有机污染处理技术(浓度为20-60 mg/L)。 给出了有关实验操作参数(摩尔比、灯功率等)的结论。
This paper discusses the use of hydrogen peroxide/visible- ultraviolet irradiation (H2O2/Vis-UV) to remove organics from water. Chemical mechanisms, including photochemistry and photo adsorption, quantum yield, and UV irradiation and decomposition of hydrogen peroxide, are discussed. The process resulted in a significant increase in oxidation rate for all compounds studied compared to the oxidation rates found for hydrogen peroxide alone. The process is a successful treatment technology for organic contamination of leachates (20-60 mg/L concentration). Conclusions regarding experimental operations parameters (mole ratio, lamp wattage, etc.) are given.
