| 摘 要： | 文章建立了离子色谱法测定废气中硫酸雾的分析方法，制备好的样品经0．45um微孔滤膜抽滤，采用AS14A阴离子交换色谱柱分离，电导检测器检测，以0．8mmol／L碳酸钠和0．1mmol／L碳酸氢钠混合溶液为流动相，流速为0．5ml／min进行测定，以保留时间定性，峰面积进行定量，方法的适用范围为0．50～50mg／m3。与铬酸钡分光光度法进行比对试验，无显著性差异。该方法操作简便、灵敏度高、准确度好，实用性强，适用于大批量环境样品的分析。

| Abstract: | Ion Chromatography was adopted to determine sulfuric acid mist in waste gas. The samples were filtered by 0. 45 um mieroporous filtration membrane, separated by the IonPac AS14A anion with 0. 8 mmol/LNa2CO3 ＋ 0. 1 mmolNaHCO3 as mobile phase. The flow rate was 0. 5 ml/min, qualitative by the retention time and quantitative by the peak area. The compari- son test results show no significant difference between ion chromatography and barium Chromate Spectrophotography. Its detection range spanned from 0. 50 mg/m3 to 50 mg/m3. The method is easy to operate and has high accuracy, sensitivity and practicabili- ty, which better suits analysis of large quantities of environmental samples. |
