应用离子色谱法测定己烯-1中的氯含量

Application of an ion chromatography in determination of free chlorine content in hexene-1

阐述了一种测定己烯-1中游离氯含量的离子色谱法。用去离子水将己烯-1中游氯离子萃取出来,用容量瓶定容后,采用离子色谱法,以Na2CO3与Na HCO3混合液作淋洗液,电导检测器检测,回收率可达94.4%,相对标准偏差小于5%,该方法准确、快速。

This paper Introduced a kind of ion chromatography in determination of free chlorine content in hexene- 1.Deionized water is used to extract free chlorine from 1-hexene,the ion chromatography is used after constant volume ismade by volumetric flask,the mixed liquid of Na2CO3/Na HCO3 is as eluent mixture,and conductivity detector is used fordetection,the average recovery is 94.4%,and the relative standard deviation is less than 5%. This method is both accurateand fast.
