黄钾铁矾类Fenton法处理难降解有机物喹啉
|
摘要
喹啉是典型芳香化合物,毒性大、难降解,传统的生物法对其去除效果差,高级氧化法处理这种难降解有机物效果极佳。用水热法合成了一种类Fenton催化剂,并考察了其对喹啉的处理效果。通过对材料的表征,证实此催化剂是黄钾铁矾且具有较好的稳定性。单因素影响实验结果表明:在初始p H=3.0、催化剂投加质量浓度3.0 g/L,H2O2质量浓度500 mg/L条件下处理50 mg/L喹啉溶液1.5 h,去除率可达100%。
Quinoline is a typical aromatic compound,which is highly toxic and difficult to be degraded. The removing effect of traditional biological methods on quinoline is poor,while the advanced oxidation technology has excellent treatment effect on this kind of refractory organic matter. A kind of new Fenton-like catalyst has been synthesized by hydrothermal method,and its treatment effect on quinoline investigated. Characterization results show that the catalyst is jarosite having comparatively good stability. The single factor experimental results show that when 50 mg/L of quinoline solution is treated under the following conditions: initial pH is 3.0,mass concentration of jarosite added 3.0 g/L,mass concentration of H2 O2500 mg/L and reaction time 1.5 h,the removing rate can reach 100%.
