| 摘 要： | 建立了水样中痕量草甘膦、草铵膦和氨甲基磷酸的FMOC柱前衍生-高效液相色谱-荧光检测分析方法。草甘膦,草铵膦和氨甲基磷酸的平均加标回收率分别为94.2%、90.8%、98.6%;相对标准偏差分别为4.8%、0.68%、2.8%;方法的定性下限和定量下限分别为0.05、0.04、0.009μg/L和0.16、0.12、0.03μg/L。水样放置两天后,水样中的草甘膦、草铵膦分别降解了17.8%和19.5%,而水样经过衍生后在5天内是稳定的。

| Abstract: | A method is proposed that allows the simultaneous determination of residue glyphosate,glufosinate and aminomethylphosphonic acid(AMPA) in water samples.The method involves pre-column derivatization step with 9-fluorenylmethylchloroformate(FMOC) in borate buffer and detection based on high performance liquid chromatography(HPLC) coupled with fluorophotomeric detectior.The method produces satisfactory reliability,sensitivity,and accuracy.The mean recovery values are 94.2%,90.8%,98.6% for glyphosate,glufosinat... |
