摘　　要：通过测定4种二硫代氨基甲酸盐类杀菌剂对二硫化碳的转化率并进行土壤中的添加回收试验,借助GC-FPD(S),研究并建立了其在土壤中的残留检测方法。4种农药的转化率稳定,在土壤中的添加质量分数在0.05~2.00 mg/kg时,4种农药的平均添加回收率在84.0%~103.2%之间,相对标准偏差在1.89%~6.14%之间,在土壤中的的最小检出浓度在0.014~0.031 mg/kg之间。该方法灵敏度、准确度、精密度等均符合农药残留检测的要求。Studied and established a detection method on soil by assessed Conversion rate of carbon disulfide in four kinds of dithiocarbamates fungicide and add recovery experiment by GC-FPD（S） method. The conversion rate of 4 pesticides was stable. At 4 pesticides spiked level between 0.05-2.00 mg/kg, the average recoveries of this method in soil ranged from 84.0 %-103.2 % with the relative standard deviations of 1.89 %-6.14 %; the minimum detectable concentration at 0.014-0.031 mg/kg. The sensitivity, accuracy and precision of the method are all in line with the requirements of pesticide residue detection.
