摘　　要：目的 :探讨一种测定空气中SO2 更为灵敏、快速、方便的检测方法。方法 :利用氧化反应将SO2 转化为H2SO4,利用离子色谱测定SO42 - 含量来计算出空气中SO2 的含量。结果 :离子色谱柱分离效果好 ,样品稳定性好 ,存放1周无明显影响。8次采样相对偏差为1.4 % ,加标回收率97 %～107%。结论 :离子色谱法分析空气中SO2,方法简单、灵敏、快速、准确 ,是一种值得推荐的方法。Purpose: investigate a sensitive, rapid, and convenience method to test the contents of SO2 in air. Method: ion chromatography was used to transform SO2 to H2SO4 , the contents of SO2 in air can be calculated by the contents of SO42- . Result: ion chromatogram column is separated well, stability of specimens is good, no obviously change appears after storing for a week. Relative errors for 8 samples are 1.4%, recover rates of added standard substance were 97%～107%. Conclusion: ion chromatography used to test contents of sulphur dioxide in air is simple, sensitive, rapid, and accurate method, and is also worth of recommending for using widely.
