摘要
在光催化反应器中,采用UV/Fenton光催化氧化技术,对湖水中微囊藻毒素的光催化降解过程中各影响因子分析表明:微囊藻毒素光催化氧化降解率受光照强度、氧化剂种类及浓度、溶液pH和不同光催化体系等多因素的影响。光促催化氧化体系对MC-LR藻毒素降解具有显著的作用,在紫外光与氧化剂的协同作用下,紫外光照强度越高,越易于促进MC-LR藻毒素快速降解,降解率可到达80%以上。
The photocatalytic decomposition of microcystin-LR in a photoreactor system has been studied by the UV/Fenton technique. The effects of influential factors on decomposition of microcystin-LR in UV/Fenton system were investigated by means of experiment. The experimental results show that the photodegradation efficiency of microcystin-LR arrived up to 80% under the conditions of UV irradiation in several photocatalytic reaction systems. These results indicated that synergic effect of ultraviolet light together with oxidant within photo-assisted reaction systems impacted greatly on the photodegradation of MC-LR algae toxin.
