| 摘 要： | 研究了反应气氛和TiO2对全氟辛酸(PFOA)的光化学降解行为的影响.结果表明,在254 nm紫外光照下,PFOA光解十分微弱,加入IO4-显著增强PFOA光解.与氮气气氛相比,氧气气氛对PFOA光化学降解有抑制作用.PFOA在UV/TiO2/IO4-体系中的降解效果低于在UV/IO4-体系,反应120 min时,PF...

| Abstract: | The influence of reaction atmosphere and TiO2 on photochemical decomposition of perfluorooctanoic acid(PFOA) in aqueous periodate was investigated using a type of low-pressure mercury lamps emitted at 254 nm.PFOA photolysis was slight with 254nm light irradiation under nitrogen,whereas significant decomposition PFOA obtained with the addition of IO 4-.In addition,oxygen restrained photochemical decomposition of PFOA.In UV /TiO2 /IO 4-system,PFOA degradation ratio was 54%,15% lower than that for UV /IO 4-sys... |
