| 摘 要： | 针对传统工艺难以去除水中抗生素微污染的问题，采用UV工艺对水中残留的环丙沙星（Ciprofloxacin，CIP）进行降解试验，研究其氧化降解速率，分析了初始反应物浓度、反应液pH值、H2O2投加量、水中不同阴阳离子对环丙沙星去除率的影响.试验结果表明，随着反应物初始浓度的升高，UV降解CIP反应速率降低，反应物初始浓度从1mg/L增加至20mg/L时，降解速率常数由0.0322min-1降低至0.0147min-1，降解最适合条件发生在中性pH值下；在UV/H2O2系统中，H2O2投加浓度存在最佳值，为1mg/L；阴阳离子对UV降解环丙沙星的影响不同，阴离子体系反应降解常数顺序依次为NO-3>SO 2-4>CO 2-3，阳离子体系反应降解常数顺序依次为Ca 2+>Mg 2+>Cu 2+.

| Abstract: | To solve the problem that the slight pollution of antibiotics in aqueous solution was hard to be removed with the traditional technologies,the degradation tests for residual ciprofloxacin(CIP) in aqueous solution were carried out with the UV technology,and the oxidative degradation rate of CIP was studied.The effect of initial concentration of reactant,pH value of reaction solution,adding dosage of hydrogen peroxide as well as different anions and cations on the removal rate of CIP was discussed.The results... |
