Abstract

A simple, sensitive and convenient ion chromatography(IC) method was established for the simultaneous determination of twelve water-soluble inorganic anions(F- , Cl- , NO2(-), NO3(-), SO3(2-), SO4(2-) , PO4(3-)), and fifteen water-soluble organic ions(formate, acetate, MSA, oxalate, malonate, succinate, phthalates, etc.) in atmospheric aerosols. The linear concentrations ranged from 0.005 microg/m3 to 500 microg/m3 ( r = 0.999-0.9999). The relative standard deviation (RSD) were 0.43%-2.00% and the detection limits were from 2.7 ng/m3 to 88 ng/m3. The proposed method was successfully applied to the simultaneous determination of those inorganic ions and organic ions in PM2.5 of Beijing.

摘要

建立了一种简单、灵敏且便捷的离子色谱（IC）法，用于同时测定大气气溶胶中12种水溶性无机阴离子（F-、Cl-、NO2(-)、NO3(-)、SO3(2-)、SO4(2-)、PO4(3-)）和15种水溶性有机离子（甲酸根、乙酸根、甲磺酸、草酸根、丙二酸根、琥珀酸根、邻苯二甲酸根等）。线性浓度范围为0.005 μg/m3至500 μg/m3（r = 0.999 - 0.9999）。相对标准偏差（RSD）为0.43% - 2.00%，检测限为2.7 ng/m3至88 ng/m3。该方法成功应用于北京PM2.5中这些无机离子和有机离子的同时测定。
