GCMS测定小麦中敌草快残留量方法的研究与改进

Study and Improvement of GCMS Method for the Determination of Dichlor Residues in Wheat

改进GCMS测定小麦中敌草快残留量的测定方法,对前处理方法进行优化改进,用纯水代替95%乙醇做提取剂,用硼氢化钾代替硼氢化钠做衍生试剂,增加了超声波提取法提取。建立了测定小麦粉中敌草快残留量的气相色谱-质谱联用法。

To improve the determination method of diquat residue in Wheat by GCMS, optimize and improve the pretreatment method, use pure water instead of 95% ethanol as extractant, use potassium borohydride instead of sodium borohydride as derivative reagent, and add ultrasonic extraction method. A gas chromatography-mass spectrometry (GC-MS) method was developed for the determination of diquat residues in wheat flour.
