摘　　要：磺胺嘧啶钠是环境中存在的广谱性抗生素,其对生态环境的危害日益受到关注。本文研究了天然水体中磺胺嘧啶钠在254nm紫外光辐射下的环境行为,考察了浓度、酸度对其光降解的影响,并通过化学耗氧量分析研究其光化学命运。试验结果表明,紫外光能够较快降解磺胺嘧啶钠。Sulfadiazine sodium is a wide used antibiotic,which is often identified in the environment.There is a growing concern about its harm to the ecological environment.This work investigates the photochemical degradation of sulfadiazine sodium in natural water under 254 nm UV radiation conditions.The effect of concentration and acidity to its photolysis was investigated,and the photochemical fate through the analysis of chemical oxygen demand.The results showed that sodium sulfadiazine 254 nm ultraviolet light to rapid degradation of.
