采用溶解-相转化法制备负载氧化铁的聚醚砜混合膜,利用扫描电镜(SEM)和热重(TG)对膜进行表征,并以酸性紫FBL为目标污染物,研究了膜活化过硫酸钠降解酸性紫FBL的性能。考察了氧化铁负载量、过硫酸钠氧化剂浓度、初始污染物浓度及温度对酸性紫FBL降解的影响,并进行膜重复实验使用性能测试。结果表明,氧化铁负载量为8%,膜活化过硫酸钠降解效果最好;氧化剂的浓度、初始污染物浓度及温度均与降解效果有关;膜活化剂重复使用5次后,经降解3.0 h,酸性紫FBL降解率仍达80%以上。 The films were characterized by scanning electron microscopy (SEM) and thermogravimetry (TG), and the acid purple FBL as the target pollutant. The effects of membrane-activated persulfate Sodium Degradation Acid Purple FBL Properties. The effects of iron oxide loading, sodium persulfate oxidant concentration, initial pollutant concentration and temperature on the degradation of acid violet FBL were investigated. The performance of the membrane was tested repeatedly. The results showed that the loading of iron oxide was 8%, and the degradation of membrane-activated sodium persulfate was the best. The concentration of oxidant, initial pollutant concentration and temperature were related to the degradation effect. After the membrane activator was reused for 5 times, , Acid purple FBL degradation rate is still above 80%.
