| 摘 要： | 实验利用O3/UV,O3/TiO2/UV,O3/VO2/TiO2降解了磺基水杨酸.结果表明,在这三种高级氧化技术中,O3/VO2/TiO2的氧化效果最好,如在相同的条件下,30 min后取样表明三者COD的去除率分别为47%,55%和70%.在不同pH条件下研究表明O3/TiO2/UV对水体pH的影响较为敏感.通过加入自由基猝灭剂研究表明三者产生羟基自由基的活性顺序是O3/VO2/TiO2＞O3/TiO2/UV＞O3/UV.

| Abstract: | Three ways(O 3/UV,O 3/TiO 2/UV,O 3/VO 2/TiO 2 )have been used to degrade the sulfosalicylic acid in this experiment.The results show that the affect of O 3/VO 2/TiO 2 on the sulfosalicylic acid is the best in three ad-vanced oxidation process .In the same experimental conditions,the results after30minutes show that t he removal of COD in three advanced oxidation process are47%,55%,and70 %,respectively.The results under different pH conditions show that O 3/TiO 2/UV is more sensitive to the pH of waterbody.In the presence of scavenger ,the results show that the order of the activity of hydroxyl radical in three a dvanced oxidation process is O 3/VO 2/TiO 2 >O 3/TiO 2/UV>O 3/UV. |
