| 摘 要： | 建立了离子色谱法快速测定乙胺类物质中氯离子的方法。通过简单的阀切换,去除大量的乙胺类物质,将氯离子富集在浓缩柱上,从而达到基体消除的目的,然后进行样品测定。在1.0～500.0μg/L浓度范围内,氯离子的线性相关系数为0.9999,相对标准偏差小于1.2%,加标回收率在92.7%～100.3%。方法已成功应用于乙胺类物质中氯离子的测定。

| Abstract: | A method for fast determination of chloride in ethylamine substance by ion chromatography was developed. With the valve-switching technique, a large amount of ethylamine substance were eliminated from sample solution and in the meantime Cl- was accumulated on concentration column, which resulted in the removal of the matrix. The method has been successfully applied to determine the concentration of Cl- in ethylamine substance. |
