| 摘 要： | 研究了“表观”即时成膜型UV／TiO2光催化反应器降解水中有机污染物的过程中，外加氧化剂与UV／TiO2体系之间的协同效应。在UV／TiO2体系中单独投加H2O2或O3可以提高光催化氧化有机污染物的速率和效率，同时投加H2O2和O3时则光催化氧化的协同作用更加显著，可大大缩短反应时间。不同反应体系的表观速率常数排序为：UV／H2O2／O3／TiO2〉UV／O3／TiO2〉UV／H2O2／TiO2〉UV／O3〉UV／H2O2〉UV／TiO2。

| Abstract: | The synergistic effect between oxidation agent and UV/TiO2 in the removal of organic pollutants using the apparent quick-prepared film photocatalytic reactor was studied. The results show that adding H2O2 or O3 into UV/TiO2 system can improve the efficiency of photocatalytic oxidation,and simultaneously adding H2O2 and O3 can achieve higher efficiency in a shorter reaction time. The different systems are listed in descending order of their photocatalytic oxidation rates:UV/H2O2/O3/TiO2>UV/O3/TiO2>UV/H2O2/Ti... |
