摘要

［Objective］The paper was to establish the method for quantitative analysis of glyphosate herbicide and identification of salt type.［Method］Using ion chromatographic column switching method,cations(sodion,ammonium ion,potassium ion,dimethonium ion and isopropylamine ion)and glyphosate anion in glyphosate salt were determined with Thermo IonPac SCS1 cation exchange column and Thermo IonPac AS14 anion exchange column,and external standard method was used for quantification.［Result］Various components showed good linear relationship within the linearity range,and the correlation coefficient r was greater than 0.999;the relative standard deviation of retention time and peak area were less than 0.13%and 1.22%,respectively;the recovery was 98.22%-99.97%.［Conclusion］The method is precise,accurate and simple,and can be used to determine the active ingredients of glyphosate herbicide.
