| 摘 要： | 以低浓度模拟苯酚废水为处理对象,研究了自制ILs-TiO2光催化剂的光催化活性,考察了苯酚废水的初始浓度、光催化剂投加量、紫外光照强度等条件对降解效率的影响,并初步探讨了其反应动力学。结果表明,ILs-TiO2光催化剂对苯酚的光催化降解反应符合一级动力学方程,光催化降解速率随苯酚的初始浓度增加而降低,催化剂的最佳投加量为300 mgTiO2/L,随着光照强度的增加,降解速率增高。

| Abstract: | The photocatalytic activities of the home made ILs -TiO2 were investigated by the degradation of phenol solution.The effects of the initial concentration of phenol , the amount of the photocatalyst and the UV light intensity on degradation rate , and the degradation kinetics were studied.The results indicated that the photocatalytic degradation of phenol decomposition reaction followed the rule of first order reaction , the rate of the decomposition was depressed by the higher initial concentration of phenol , the optimal amount of the photocatalyst was 300 mgTiO2/L, and the rate of the decomposition was heightened by the increased of UV light intensity. |
