摘要
建立了新品农药溴氟菊酯在水体及土壤中残留量的测定方法,采用石油醚+丙酮(3+1)混合溶剂提取,经浓硫酸+无水乙醇(1+1)纯化,用毛细管气相色谱电子捕获检测器测定。该法检出限为0.1×10-9~2×10-9,回收率72.6%~100.5%,变异系数1.6%~8.5%。
A new method for determination of residue broflothrin in water and soil was established.Sample was extracted with mixed solvent of petroleum ether and acetone (3+1 by volume),purified by mixture of sulfuric acid and absolute alcohol(1+1 by volume) and then determined by capillary gas chromatography using electron capture detector,with a detection limit of 0.1×10 —9 ~2×10 —9 , a recovery rate of 72.6%~100.5% and a RSD of 1.6%~8.5%。
