本文采用简便、快速的前处理方法和火焰光度检测的气相色谱法对土壤中残留的硫双威进行定量测定，硫双威在土壤中的最低检出浓度为０．０３ｍｇ／ｋｇ，平均加标回收率在９８．３１％～１０５．４％范围内，变异系数小于４％。
In this paper, a simple and rapid pretreatment method and flame photometric detection of gas chromatography residue thiosulfan in soil quantitative determination of thiosulfan in soil minimum detectable concentration of 0.03mg / kg, the average spiking The recoveries ranged from 98.31% to 105.4% with a coefficient of variation of less than 4%.
