| 摘 要： | 以亚铁离子活化过硫酸氢钾（PMS）所产生的硫酸根自由基为氧化剂，氧化水中的酮洛芬，考察了pH值、温度、Fe2+浓度、Fe2+/PMS摩尔比以及Fe2+投加方式等因素对酮洛芬氧化降解的影响，探究氧化降解酮洛芬（KTP）的最佳运行条件。结果表明，在实验范围内，pH值为3、温度为45℃和Fe2+/PMS/KTP浓度比为20/15/1时酮洛芬的降解效果最好，酮洛芬的去除率达到66.8%。分批式投加Fe2+，使硫酸根自由基（SO4·-）持续生成，这样更有利于酮洛芬的降解。

| Abstract: | The SO4·- species generated by Fe2+-activated peroxymonosulfate (Fe2+/PMS) were utilized to oxidize KTP in water. Experiments were conducted to determine the optimal conditions for KTP degradation; specifically, the pH, temperature, Fe2+ concentration, Fe2+/PMS/KTP molar ratio, and sequential addition of Fe2+ were investigated. The results show that the maximum KTP decomposition rate (66.8%) was achieved at pH 3, 45℃ and a Fe2+/PMS/KTP molar ratio of 20/15/1. The sequential addition of Fe2+ indicated that a consistent production of sulfate radicals was beneficial for the KTP degradation. |
