【摘要】 介绍了用离子色谱法测定大气总悬浮颗粒物（TSP）中的F^-、Cl^-、SO₄^2-、NO₃^-,对过氯乙烯采样滤膜用去离子水作为提取液进行超声波提取。方法的平均回收率分别为F^- 98.7%,Cl^- 103%,SO₄^2- 97.8%,NO₃^- 101%。相对标准偏差为F^- 0.29%,Cl^- 0.32%,SO₄^2- 0.25%,NO₃^- 0.30%。更多还原

【Abstract】 A method for the determination of F^-、Cl^-、SO₄^2-、NO₃^- in total suspended particulate matter（ TSPs） by ion chromatography is presented. Ultrasonic extraction of perchloroethylene sampling membrane with deionized water as extract.The average recoveries of the method were F^- 98. 7%,Cl^- 103%,SO₄^2- 97. 8%,NO₃^- 101%.The relative standard deviation were F^- 0. 29%,Cl^- 0. 32%,SO₄^2- 0. 25%,NO₃^- 0. 30%.更多还原
