本标准规定了测定环境空气颗粒物中水溶性阴离子(F-、Cl-、Br-、NO2-、NO3-、PO43-、SO32-、SO42-)的离子色谱法。
本标准适用于环境空气颗粒物(包括TSP、PM10、PM2.5、降尘等)中8 种水溶性阴离子
(F-、Cl-、Br-、NO2
-、NO3
-、PO4
3-、SO3
2-、SO4
2-)的测定。
环境空气颗粒物滤膜样品,当采样体积为60 m3(标准状态),提取液体积为100 ml,
进样体积为25 μl 时,本方法的检出限为0.010 μg/m3 ~ 0.085 μg/m3,测定下限为0.040 μg/m3 ~
0.340 μg/m3;降尘样品,当取样量为0.100 g,提取液体积为100 ml,进样体积为25 μl 时,本方法的检出限为0.006 mg/g ~ 0.051 mg/g,测定下限为0.024 mg/g ~ 0.204 mg/g。详见附录A。
注1:本方法也适用于在特殊天气下,采集的颗粒物(如沙尘气溶胶和沙尘暴降尘)样品的分析。
Scope
This standard specifies an ion chromatographic method for the determination of water-soluble anions (F−, Cl−, Br−, NO2−, NO3−, PO43−, SO32−, SO42−) in ambient air particulate matter. This standard applies to 8 water-soluble anions (F−, Cl−, Br−, NO2−, NO3−, PO43−, SO32−, SO42−) in ambient air particulate matter (including TSP, PM10, PM2.5, dust, etc.) ) determination. For ambient air particle filter membrane samples, when the sampling volume (standard state) is 60 m3, the extraction liquid volume is 100 ml, and the injection volume is 25 ml, the detection limit of this method is 0.010~0.085 mg/m3, and the lower limit of determination is 0.040~0.340 mg/m3; dust sample, when sampling
