摘 要：
[Aims] A quantitative analytical method for gluofosinate-ammonium by nuclear magnetic resonance spectrometry was developed. [Methods] The heavy water was used as solvent and 1-(sec-butyl)urea was used as internal standard. The methyl peak at d 1.27 of gluofosinate-ammonium and the methyl peak at d 1.11 of 1-(sec-butyl)urea were used for quantifi cation. [Results] Linear regression of quantitative peak areas ratio(As/Ai) versus mass ratio(Ws/Wi) of gluofosinate-ammonium to 1-(sec-butyl)urea yielded a correlation coefficient of 0.999 9. The variation coefficient for determination the content of the same batch sample was 0.22%. [Conclusions] This method could be used to determination of content of gluofosinate-ammonium without the standard of gluofosinate-ammonium.
