摘要: 利用TiO2纳米管催化降解水中的4，4’-二溴联苯，对催化降解过程和影响因素进行研究。结果表明，TiO2纳米管对其有较高的催化降解效率且降解过程符合Langmuir-Hinshelwood动力学模式。不同光源、4，4’-二溴联苯的初始浓度、纳米管添加量和pH值对催化降解过程都有较大影响，其中pH值的影响最为明显。反应液在中性状态下的降解率明显低于pH=1或11的情况。在pH=1时，4，4’-二溴联苯的降解率达86%。

Abstract: The efficiency and influencing factors of the photocatalytic degradation of 4，4’-DBB in water were studied using TiO2 nanotubular as photocatalyst under UV irradiation. The results show that the photocatalytic degradation of 4，4’-DBB in water by TiO2 nanotubular is efficient. The degradation of 4，4’-DBB follows the Langmuir-Hinshelwood kinetics reaction. The experiments show that several parameters have great impacts on the photocatalytic degradation process such as light source，4，4’-DBB initial concentration，nanotubular amount，pH value and so on. And pH plays an important role in the degradation process. Higher degradation rates are reached in pH=1 or pH=11 solution and lower in neutral solution. The degradation rate of 4，4’-DBB is 86% at pH=1.
