活性炭搭载TiO_2降解溴化乙锭的试验研究

不同光源、光照时间、催化剂的用量和溶液的pH来分析降解溴化乙锭(EB)的效率,同时比较了纳米TiO2降解EB、掺杂Fe3+的TiO2降解EB和负载活性炭的TiO2降解EB的效率.实验结果表明:TiO2对EB的降解具有较好的效果.而在制备TiO2催化剂的时候,将TiO2负载到活性炭上对EB的降解效果最好,而且便于催化剂的回收.对于20 mL,1μg/mL的EB溶液,用60mgTiO2/AC作为催化剂、溶液pH=9.6、在紫外灯下照射2.5h,能达到最佳的降解效果.

Study of TiO2 with Activated Carbon on Degradation of EB

This is designed TiO2 with activated carbon on degradation of EB,this article analyzed the efficiency of degradation of EB from the different light source,the light time,the amount of catalyst solution and the pH value.At the same time,compared Nano-TiO2 the degradation of EB,Fe3＋ doping TiO2 degradation of the EB and TiO2 load the activated carbon degradation of the efficiency of the EB.It is shown that TiO2 has good effect on the degradation of EB.TiO2 catalyst in the preparation of the time,TiO2 load on the activated carbon to the degradation of EB is the best,and the catalyst easied for recovery.For 20 mL,1 μg/mL solution of the EB,and 60 mg TiO2/AC as a catalyst,so that the solution pH is 9.6,in the ultraviolet irradiation 2.5 h,the degradation can achieve the best results.
