  • 摘要: 萘普生为水体中常见的一种非甾体药物类污染物。以300W汞灯为光源,研究紫外光照降解法对于含低浓度萘普生废水的处理效果,发现pH对萘普生光解效果有直接影响,降解优异性顺序为酸性＞碱性＞中性。通过实验,确定了萘普生光解的最佳pH值为4,光照时间为40 min,在该实验条件下,萘普生的降解率达到97.6%。通过液相色谱-质谱联用法对降解后水样进行检测,初步推导出光解中间产物为6-甲氧基-2-乙酰基萘、6-甲氧基-2-乙烯萘及β-萘酚。
    Abstract: Naproxen was a common non-steroidal drugs pollutant in water. With 300W mercury lamp as the light source, the photodegradation of naproxen in low concentration was studied.The results showed that pH had a direct impact on the photolysis of naproxen,the sequence of degradation was acidity >alkalinity >neutral,the optimum pH was 4, the illumination time was 40 min.Under these conditions,the conversion was high as 97.6%.A high-performance liquid chromatography-tandem mass spectrometric method(LC-MS/MS)was used to analyse the degradation water sample.Referred to the analyse results, it was preliminarily deduced that the photolysis intermediates were 6-methoxy-2-acetyl-naphthalene, 6-methoxy-2-vinyl naphthalene and β-naphthol.
