臭氧氧化降解水中吉非罗齐的效能和影响因素研究

Study on the Degradation Efficiency and Influencing Factors of Ozonation of Gemfibrozil in Water

指出了药品和个人护理品(PPCPs)在水环境中广泛存在,对人们的身体健康构成潜在威胁。以使用吉非罗齐作为目标污染物,考察了臭氧浓度、吉非罗齐初始浓度、溶液pH值和不同水体对臭氧氧化降解水中吉非罗齐的影响。实验结果表明:臭氧氧化技术可以高效降解水中的吉非罗齐,在中性或弱碱性环境,臭氧浓度0.5mg/L,吉非罗齐浓度为300μg/L的条件下可达到最佳的降解效果。

Pharmaceutical and personal care products(PPCPs)widely exist in the water environment and pose a potential threat to people's health.In this study,gemfibrozil was used as the target pollutant to investigate the effect of ozone concentration,initial concentration of gemfibrozil,solution pH and different water bodies on the degradation of gemfibrozil in water by ozonation.The experimental results show that the ozonation technology can effectively degrade the gemfibrozil in water.In neutral or weak alkaline solution,the best degradation efficiency can be achieved when the concentration of ozone is 0.5mg?L^-1 and the concentration of gemfibrozil is 300 pig L^-1.
