摘　　要：建立草铵膦原药中氯离子的离子色谱定量分析方法。试样用超纯水溶解,以5mmol/L氢氧化钾水溶液为流动相,用AS12A色谱柱(含AS12A保护柱)和电导检测器,对草铵膦原药中氯离子进行定量分析,外标法定量。方法线性相关系数为0.999 4,变异系数是1.9%,平均回收率为100.1%。该方法操作简单,重复性好,可用于定量分析草铵膦中氯离子。To establish a quantitative analysis method for the determination of chloride ion in glu- fosinate- ammonium TC by Ion chromatography. The samples was dissolved ultrapure water and analyzed by Ion chromatography using AS12A column （including AS12Aguard column）, con- ductivity detector and 5 mmol/L potassium hydroxide aqueous solution as mobile phase. The content of chloride ion was quantified by external standard method. The linearity coefficient was 0. 999 4, the variation is 1.9% and the average recovery is 100. 1%. The method is simple, reproducible and could be used to detect the chloride ion in glufosinate -ammonium TC.
