| 摘 要： | 采用UV、H2O2、UV/H2O2、Fenton、UV/Fenton和UV/TiO2方法，对水中低浓度的药物甲硝唑进行降解。通过HPLC和UV-Vis光谱得到的甲硝唑去除率。详细讨论了Fe2+、TiO2和H2O2的初始浓度以及溶液的初始pH值对降解效率的影响。结果表明，UV/Fenton和UV/TiO2 2种系统对水中低浓度甲硝唑均有很好的去除效果，但前者的光催化效率更高。在甲硝唑浓度=6 μmol/L，H2O2和Fe2+的初始浓度分别为0.5 mg/L和2.94 μmol/L，pH=4的条件下，UV/Fenton方法对甲硝唑水溶液光催化的最佳效率为95.8%。

| Abstract: | The photocatalytic degradation of the metronidazole was carried out by means of the UV,H2O2,UV/H2O2,Fenton,UV/Fenton,UV/TiO2 advanced oxidation processes.The drug degradation was monitored during the experiment with HPLC and UV-Vis Absorption.The effects of the initial concentrations,for instance Fe2+,TiO2,H2O2,as well as the solution pH on the removal of the drug were discussed.The result suggests that UV/Fenton and UV/TiO2 systems can remove the drug more efficiently from the waters containing metronidazo... |
