Glyphosate (C3H8NO5P) is a widely used herbicide in agricultural production. It has broad spectrum and high efficiency, low toxicity, easy decomposition and no residue. Glyphosate is a great hazard to organisms, which may cause excessive excitement, movement disorder, coma, paralysis of the respiratory center and even death. The sanitary limit value of glyphosate in domestic drinking water standards is 0.7mg/L. Common glyphosate inspection methods are spectrophotometry, liquid chromatography, and liquid chromatography. However, the photometric method has large error and low sensitivity; liquid chromatography requires complex pretreatment process, and sample preparation is complicated; liquid chromatography and mass spectrometry costs are high. In this paper, the ion chromatographic conductivity detection method is used to determine the glyphosate content in drinking water, eliminating the complicated pretreatment method and simultaneously measuring other anion indexes in water. The method is simple, accurate and sensitive, and is especially suitable for simultaneous quantitative determination of glyphosate and various conventional anions in drinking water.
