湿性样品中的多来宝残留物用丙酮(水样和干样用石油醚)提取, 提取液经石油醚再萃取、浓缩后、用被后石油醚饱和的乙腈分配, 过硅胶氧化铝混合柱净化, 室温下与(CH3)3SiI衍生化反应, 生成了-苯氧基-苄基碘, 用GC检测。当添加浓度为0.05,0.10, 1.00μg/g时, 样品的平均回收率为80.7%_110.0%, 方法最小检出量为0.01ng, 样品最小检出浓度为: 水0.001mg/L, 稻米和土壤0.01μg/g, 稻草、谷壳、水浮莲和罗非鱼0.008μg/g。(图3表1参4)

The residue of Trebon insecticide in wet environmental samples is extracted with acetone (water sample and dry sample with petroleum ether) and the extract is reextracted with petroleum ether. After being concentrated by evaporation, the reextract is partitioned by acetonitrile saturated with petroleum ether. The residue of the acetonitrile phase is cleaned up by column chromatography on an mixture of alumina and silica gel. By treating the residue with iodotrimethylsilane at room temperature, 3 phenoxybenzyliodide is obtained from Trebon. The ...
