| 摘 要： | 以TiO2为光催化剂，在紫外光照射下降解处理低浓度苯酚模拟废水，并以紫外一可见分光光度法作为分析手段，考察了TiO2光催化剂浓度对苯酚降解过程的影响。结果表明，当苯酚浓度为40mg／L时，TiO2光催化剂的最佳浓度为1．0g／L，此时苯酚去除率较高，达23．49％。同时对降解动力学的研究表明，苯酚的光催化降解过程符合一级反应动力学模式。

| Abstract: | TiO2 was used as the photocatalyst for treating the simulated wastewater containing low concentration phenol through degradation under the irradiation of UV light, and UV - vis light spectrophotometry was adopted for studying the effect of the concentration of TiO2 photocatalyst on the degradation of phenol. The results have shown that the optimum concentration of TiO2 photocatalyst is 1.0 g/L when the concentration of phenol is 40mg/L, at which the removal rate of phenol is high and can reach 23.49%. The study on degradation kinetics has shown that the degradation of phenol by photocatalyst is in accordance with the first -order reaction dynamic model. |
