摘　　要：通过衍生化反应和气相色谱检测来测定稻田水、土壤样品中氟草烟的残留。氟草烟的最小检出量为2.0×10-12g,最低检出质量分数稻田水中为0.001mg/kg、土壤中为0.002mg/L。稻田水中氟草烟的平均添加回收率为96.16%￣103.20%,变异系数为2.34%￣6.97%;土壤中的平均添加回收率为81.35%￣94.27%,变异系数为4.26%￣6.52%。Determined the residue of fluroxypyr in paddy field water and soil by derivative reaction and GC. The minimum detectable amount of fluroxypyr was 2.0 × 10^-12g, and the minimum detectable mass fraction in water and paddy soil were 0.001 and 0.002 mg/L, respectively. The average of recoveries of fluroxypyr were 96.16-103.20% for water samples and 81.35-94.27% for paddy soil samples. The coefficient of variations of fluroxypyr were 2.34-6.97% for water samples and 4.26-6.52% for paddy soil samples.
