离子色谱法同时检测高氯酸钾中的氯酸盐和氯化物分析

Determination of Chlorate and Chloride in Potassium Perchlorate by Ion Chromatography

为快速将高氯酸钾中氯酸盐及氯化物测定,文章主要采用离子色谱法,该方式具有较多优势,不仅操作简单、便捷,而且测定结果准确性较高。该方法测定其氯酸盐及氯化物回收率分别为99.1%和102.3%,且两者物质浓度检出限分别为12.4μg/L和10.6μg/L,同时检测ClO4-、CIO3-和CIO2-含量处于1~100μg/L时,其线形关系较佳,且系数超过0.995,当其三种离子含量高于100μg/L时,相关系数超过0.991。

For rapid determination of chlorate and chloride in potassium perchlorate,This paper mainly uses ion chromatography,This approach has many advantages,Not only is it simple and convenient,And the accuracy of the determination results is high.The recoveries of chlorate and chloride were 99.1%and 102.3%,respectively,The detection limits were 12.4μg/L and 10.6μg/L,respectively When the ClO4-、CIO3-and CIO2-contents are 1~100μg/L,Its linear relationship is better,And the coefficient exceeds 0.995,And when the three ions are above 100 ug/L,The correlation coefficient is more than 0.991.
