  • 摘要: 建立一种采用离子色谱仪同时测定空气亚微米细颗粒物（PM1.0）中5种水溶性离子（F-、Cl-、NO3-、SO42-、NH4+）的方法，分析了北京市东部某城区2017-2018采暖季PM1.0中主要水溶性离子的含量和污染特征.采用石英纤维滤膜采集居住区环境空气样品，经超纯水超声浸提洗脱后，F-、Cl-、NO3-、SO42-选用岛津IC-SA2柱，以碳酸钠/碳酸氢钠溶液作为淋洗液进行分离，NH4+选用岛津IC-C4柱，以草酸溶液作为淋洗液进行分离，经电导检测器测定.F-、Cl-、NO3-、SO42-、NH4+在0.078-25 μg·mL-1线性范围内线性相关系数≥ 0.9990，方法精密度在0.016%-0.76%之间，对标准参考物质进行分析，测定结果符合参考值.
    Abstract: A method for simultaneous determination of five water-soluble ions (F-,Cl-,NO3-,SO42-,NH4+) in airborne submicrometer particles was established. And the method was used to analyze the contents of the water-soluble ions in airborne submicrometer particles collected in east urban Beijing during 2017-2018 heating season. The airborne submicrometer particle samples in residential areas in the east of urban Beijing were collected using quartz fiber filter membrane. After ultrasonic extraction with ultra-pure water, the contents of F-,Cl-,NO3-,SO42- and NH4+ were determined simultaneously by ion chromatography. Shimazin IC-SA2 column was chosen for separation of F-,Cl-,NO3-,SO42- with sodium carbonate/sodium bicarbonate solution as leaching solutions, and Shimazin IC-C4 column was for NH4+ separation with oxalic acid solution as leaching solution. The conductivity detector was used. The linear correlation coefficients of F-,Cl-,NO3-,SO42- and NH4+ were not less than 0.9990 within the linear range of 0.078-25 μg·mL-1, and the RSD was in the range of 0.016%-0.76%.
