离子色谱法测定固定污染源排气中的氯化物和硝酸盐

Determination of chloride and nitrate in stationary source emission by ion chromatography

介绍了用离子色谱法测定固定污染源排气中的Cl^-和NO_3^-,测试结果表明,相对标准偏差分别为Cl^-2.1％,NO_3^- 2.4％;平均回收率为Cl^- 105％,NO_3^- 102％,是一种简便快速、准确可行的方法。

In the paper the method used for the determination of chloride and nitrate in stationary source emission by ion chromatography was presented. The results obtained by this method showed the relative standard deviations for Cl-and NO3-were 2.1% and 2.4% respectively and the average recoveries were 105% and 102% respectively.This method possesses better recovery and precision.
