摘　　要：建立草甘膦钾盐水剂的鉴别检测方法。以5 mmol/L甲磺酸水溶液为流动相,采用CS 12A离子色谱柱(含CG 12A保护柱)以及电导检测器对草甘膦钾盐水剂中的钾离子进行鉴别检测。结果表明:方法线性相关系数为0.999 9,标准偏差小于0.1,变异系数小于1.0%,平均回收率为100.65%。该方法能够用于鉴别检测草甘膦钾盐水剂的有效成分。The discrimination method of glyphosate-potassium AS was established by Ion Chromatography （IC） using 5 mmol/L methanesulfonic acid aqueous solution as the mobile phase, CS 12A ion column （including CG 12A guard column） and conductivity detector. The results showed that the linear correlation coefficient of the method was 0.999 9, the standard deviation was less than 0.1, the coefficient of variation was less than 1.0%, the average recovery was 100.65%. The method was precise, accurate and simple, could be used to discriminate the active ingredient in glyphosate- potassium AS.
