摘要 采用离子色谱法测定了草甘膦异丙胺盐的含量。用AS–11离子色谱柱(含AG–11离子色谱保护柱)和电导检测器、外标法对草甘膦异丙胺盐进行定性、定量分析,方法的相对标准偏差为1.60%~1.74%,标准添加回收率为98.3%~101.5%。该方法方便快速,结果准确可靠。 Determination of glyphosate-isopropylammonium by ion chromatography (IC) was described. The Glyphosate-isopropylammonium was quantitatively and qualitatively determined by IC with a conductivity detector, a AG-11 and AS-11 column, and an external standard. Relative standard deviation was 1.60% to 1.74%, and average recoveries between 98.3% and 101.5% were obtained for spiked samples. The method is simple, rapid, accurate and reliable.
