| 摘 要： | 氧氟沙星（Ofloxacin，OFL）是畜禽养殖业中最常使用的抗菌药物之一，其在粪便中的残留会对微生态环境产生不利影响。本试验对3种条件下鸡粪便中氧氟沙星的降解进行了研究，结果显示，室温避光条件下，鸡粪便中氧氟沙星几乎不降解，发酵条件下OFL的降解很慢，自然光照时OFL的降解较快。 OFL降解的变化趋势符合一级动力学方程Ct=C0e-kt，根据此方程求得光照条件下的OFL降解半衰期为(5.77±0.466) d， 发酵条件下的OFL降解半衰期为(35.66±1.99) d。

| Abstract: | Ofloxacin is one of the most widely used antibiotics in the livestock and poultry industry,its residue in the excrement will has the adverse effect to the environment.Ofloxacin's degeneration in the chicken excrement had been studied in different conditions.The results showed that ofloxacin in chicken excrement was very stable in photophobic condition,the degradation rate of ofloxacin was slow in the chicken excrement of fermentation,but under daylight illumination,the degradation rate of ofloxacin was high... |
