离子色谱法测定空气中二氧化硫

摘要

Objective To explore the new determination method of sulfur dioxide in air with ion chromatography. Methods A new method of the determination of sulfur dioxide in air with ion chromatography was proposed. Results In the condition of ion chromatography, a good correlation coef icient ( r=0.9994) was obtained with the linear range of 1~50μg/ml for SO42-, and the limit of deteciton was 0.01μg/ml. Conclusion The new method possessed many advangtages including easily control, sensitive, precision and could met the determination of sulfur dioxide in real air samples.%目的：探索离子色谱法测定空气中二氧化硫的测定方法。方法建立离子色谱法测定空气中二氧化硫的测定方法。结果在一定的离子色谱条件下,SO42-在1~50μg/ml范围内具有良好的线性关系,相关系数r0.9994,检出限0.01μg/ml,回收率95.2~106.8%。结论离子色谱法实验条件容易控制,方法灵敏,精密度高,能满足空气中二氧化硫的测定。
