稻米和土壤中农美利残留量气相色谱分析方法的研究

Study on Analytical Approach for Nominee Residue in Rice and Soil by Gas Chromatography

建立了测定稻田土壤、稻米中农美利残留量的气相色谱分析方法。用配有NPD的气相色谱仪、DB 1301毛细管柱测定稻田土壤及稻米中农美利的残留量,最低检测浓度为0.01mg/kg、平均回收率为80.4%～99.8%,变异系数为6.3%～11.7%,均达到残留分析的要求。

A gas chromatographic approach was developed for determining Nominee residue in soil and rice. Using gas chromatograph equipped with NPD and DB-1301 capillary column,the detection limit is 0.01mg/kg,the mean recovery is 80.4%～99.8%, and the coefficient of variation is 6.3%～11.7%.The approach has higher sensitivity and less interference.
