摘要
采用阳极氧化法制备TiO2纳米管电极,用SEM等方法对光电极的表面形貌进行了表征。以罗丹明B为目标污染物确定最佳退火温度,制备的电极进行壬基酚降解实验,实验通过添加自然界中分布较广的SO42-、Cl-阴离子来观察对壬基酚降解效果的影响。结果表明在退火温度为550℃时罗丹明B的降解效果最好为67.31%。用TiO2纳米管电极降解壬基酚时,不添加阴离子条件下的对壬基酚的降解效率达到91.66%要高于添加Cl(-65.99%)、SO42-(65.73%)
In this study,TiO2 nanotube electrode is prepared by anodic oxidation.SEM is used to characterize the electrode surface morphology.Rhodamine B as the target pollutants determines the optimal annealing temperature.Then it uses the electrode under the conditions to complete nonylphenol degradation experiment.Experiment by adding SO42-,Cl-to observe the effect on the degradation of nonylphenol.Seeing from the experiment,in the annealing temperature of 550 ℃,the degradation of Rhodamine B is highest.Nonylphenol degradation with TiO2 nanotubes electrode is 91.66%,and it would have a negative impact when added Cl（-65.99%）,SO42（-65.73%）.
