摘　　要：由于在高真空条件下制得的草铵膦铵盐极易吸水,本法将铵盐制成水剂后采用高效液相色谱分析定量测定草铵膦含量,计算反应收率。以0.05 mol/L磷酸二氢钾水溶液为流动相、调pH值至3.5,流速为1.3 mL/min,检测波长为195 nm,柱温30℃,对草铵膦铵盐粗品中有效成分进行高效液相色谱测定。该法线性良好,具有较高的精密度和准确度,是一种较理想的分析方法。The Glufosinate-ammonium prepared in high vacuum conditions is extremely easy to absorb water. So a method for quantitative determination of glufosinate-ammonium by HPLC was established to calculate the reaction yield. The operating conditions were as follows： 0.05 mol/L phosphate buffer （KH2PO4） as mobile phase, pH at 3.5 with the flow rate of 1.3 mL/min, DAD detector wavelength at 195 nm and Nucleosio SB ion exchange colomun at 30℃. This is a better method for quantitative determination with good linearity and relatively high precision and accuracy.
