Determination of Atrazine in Drinking Water Source by High Performance Liquid Chromatography
This article establishes a high-performance liquid chromatography method for determining the content of atrazine in drinking water sources.The experiment used Eclipse XDB-C18 chromatography column(150 mm×4.6 mm,5 μm),the detection wavelength is 225 nm,the column temperature is 25℃,and the mobile phase is water∶methanol=30∶70(volume ratio),the injection amount is 10 μL,flow rate of 0.8 mL·min-1,isocratic elution,combined with solid-phase extraction to determine the content of atrazine in drinking water.The results indicate that the method has high sensitivity and good reproducibility,and is suitable for the determination of atrazine in water.
