摘要
研究了在实验室条件下O3/UV工艺对BDE47去除效率的影响,考察了影响降解效率的因子,如溶液的初始浓度、O3转化率和pH值等,分析了臭氧和紫外的协同作用,探讨了动力学反应.结果表明,O3/UV对BDE47的降解效率随着pH值的升高、臭氧转化率的提高和UV强度的增强而升高,随初始浓度增加,去除效率降低;O3和UV具有很好的协同作用,对BDE47的去除效果明显;BDE47的去除基本符合伪一级反应动力学规律.
In this paper, the degradation ratio of BDE47 was investigated using O3 /UV technology. Influence factors, such as the initial concentration, percent conversion of O3 and pH values, on removal of BDE47 were studied. The synergy between O3 and UV were analyzed, further, reaction dynamics was discussed.The results indicated thatthe degradation of BDE47followed the pseudo-order kinetics.
