摘要
研究了青菜7种有机磷农药残留检测技术。以丙酮、石油醚为萃取溶剂,用超声波法提取,并以气相色谱法火焰光度检测器(GC-FPD)进行测定。结果表明,该方法的添加回收率和变异系数均符合农药残留分析的要求。
A mulitiresidue method for determination of organophosphorus pesticide was developed. The samples were extracted by ultrasonic extraction with acetone/petroleum ether. The extract was deterrained by GC-FPD. The recovery and CV were up to the pesticide residue analysis.
