| 摘 要： | 自行制备负载型TiO2催化剂,对苯胺水样进行了光助催化。探讨了初始底物浓度、催化剂用量、光照强度及微量H2O2对降解率的影响。结果显示,TiO2光助催化降解苯胺效果良好,当苯胺浓度低于2mmol.L-1时,降解率在98%以上,催化剂量、光源强度和微量H2O2都可提高苯胺的降解率。进一步研究可知苯胺经催化降解后,苯环被打开,有助于后续的生化处理。

| Abstract: | The self-made immobilized TiO2 was used as photocatalyst to degrade phenylamine water sample.Some operating parameters,including initial concentration,catalyst dosis,light intensity and trace H2O2,are conducted in this research.The degradation rate is more than 98% when phenylamine concentration is lower than 2 mmol/L.Catalyst dosis,UV light intensity and trace H2O2 can increase the degradation rate of phenylamine.Further studies show benzene ring was broken after it was catalysed.It is helpful for later biochemical treatment. |
