Abstract: The inorganic ions (fluoride, chloride, nitrate, sulfate, calcium, ammonium, sodium, magnesium, potassium) in aerosol samples were analyzed by capillary electrophoresis (CE) and ion chromatography (IC). The results showed that the correlation between the peak area and concentrations was good. The linear range and repeatability can meet the need of general aerosol samples measurement. The aerosol samples collected in Beijing were quantitatively analyzed with this method. The concentrations obtained by CE have a good agreement with those by ion chromatography (IC). Ｔ-test showed that there is no notable difference between the concentrations determined by the two methods.

摘要： 研究了用毛细管电泳法测量气溶胶中无机离子（F^-，Cl^-，NO₃^-，SO₄^2-，Na^＋，NH₄^＋，K⁺，Mg²⁺，Ca²⁺）组分的方法。结果表明，用这种方法得到的标准曲线具有良好的线性相关关系，线性范围和重复性也基本可以满足一般气溶胶样品的测量，可以达到定量测量的要求。用该方法对实际大气气溶胶样品进行了测量，测量结果与用离子色谱法测量得到的结果相关性很好，T 检验表明两结果之间无显著性差异。
