为了更全面的了解环丙沙星在自然界中的环境化学行为,采用批处理实验方法研究了环丙沙星在二氧化锰作用下的氧化转化过程,并讨论了溶液的pH对反应的影响。结果表明,在无二氧化锰的条件下,环丙沙星的质量浓度在1周内检测没有明显的变化。在二氧化锰存在的条件下,环丙沙星对二氧化锰的氧化作用具有较强的反应感受性。pH一定的条件下,当环丙沙星相对过量时,环丙沙星去除率随自身质量浓度的增大而减小,随二氧化锰质量浓度的增大而增大。此外,随着溶液 pH值由3.5升至5.9时,环丙沙星的去除率显著上升。 |

In order to have further understanding of the environmental chemistry behaviors of ciprofloxacin(CIP),oxidative transformation of CIP facilitated by MnO_2 was investigated in batch reactor systems.The effect of pH on the reaction was discussed in this paper.The control experiment showed that no appreciable loss of CIP was detected in the absence of MnO_2.The result of reaction suggested that CIP was highly susceptible to transformation mediated by MnO_2.With an excess of CIP and at a constant pH,the removal rate of CIP increased as a function of MnO_2 concentration,but decreased as a function of CIP concentration.Furthermore,the removal rate increased significantly as the solution pH increased from 3.5 to 5.9. |
