Abstract:

Norfloxacin as one of quinolone antibiotics is widely used in medical treatment, animal husbandry, agriculture, aquaculture and other industries. In recent years, the accumulation of quinolones in the environment poses a direct or potential threat to ecosystem stability, diversity and human health. Therefore, how to rapidly degrade quinolones has become an urgent problem. However, the removal efficiency of the antibiotics is limited. Therefore, in this paper, the Au-TiO2 photocatalyst was prepared, and the effects on the visible light degradation of norfloxacin were mainly studied by changing the reaction conditions such as pH, chloride concentration and Au-TiO2 amount, and the highest norfloxacin degradation rate of 80% of was obtained. This study not only proved that the visible light degradation of norfloxacin by Au-TiO2 was feasible, but also further indicated that the visible light catalytic technology was a potential method for the treatment of antibiotic wastewater.

Key words: Au-TiO2, visible-light photocatalysis, degradation, norfloxacin

摘要:

诺氟沙星作为喹诺酮类抗生素的一种,被广泛用于医疗、畜牧业、农业和水产养殖等行业,大量抗生素的生产、使用和非法排放造成水环境中抗生素污染问题日益突出,对生态系统和人类健康构成潜在的危害。而目前现有的抗生素的去除方法效率有限,本文制备了Au-TiO2光催化剂,重点研究了水中酸碱度、氯离子浓度及Au-TiO2催化剂量对Au-TiO2光催化剂可见光降解诺氟沙星的影响,获得最高80.7%的诺氟沙星的降解率。本研究不仅证明了Au-TiO2可见光高效降解诺氟沙星是可行的,也进一步表明了可见光催化技术处理抗生素废水是一种有应用潜力的方法。
