【摘要】 [方法]采用摇瓶法测定草铵膦的正辛醇/水分配系数,并用萃取法对有机相中的草铵膦进行浓缩、反相液相色谱法分别对两相中的草铵膦进行测定。[结果]萃取法的回收率为95.2%~99.3%,方法的变异系数为1.69%。[结论]方法的精密度较高,具有简便、快速的优点,适用于草铵膦的正辛醇/水分配系数测定。更多还原

【Abstract】 [Methods] Shake flask method was used to determinate the n-octanol/water partition coefficient of glufosinateammonium,the glufosinate-ammonium in organic phase was extracted and concentrated,and the glufosinate-ammonium in two phases were determined by HPLC respectively.[Results] The recovery of the extraction was between 95.2-99.3%,and the RSD of lgPow was 1.69%.[Conclusions] The method was easily and quickly performed with higher precision,which was suitable for determination of the n-octanol/water partition coefficient of glufosinate-ammonium.更多还原
