| 摘 要： | 采用超高效液相色谱法分析了氟虫双酰胺及其代谢产物在田水、土壤、稻秆、糙米和稻壳中的残留.水样以乙酸乙酯为萃取溶剂,液-液分配净化;土壤样品以丙酮为提取剂,液-液分配净化;水稻样品经乙腈提取,NH2-Carb柱净化.对水稻和环境中的氟虫双酰胺及其代谢产物进行不同水平的添加回收率实验,方法的回收率在78.2%—104.8%之间,相对标准偏差为1.1%—4.4%.氟虫双酰胺及其代谢产物的最小检出量在0.004—0.02 ng,其在稻田水中的最低检测浓度为0.0008—0.0009 mg.L-1,在土壤、稻秆、糙米、稻壳中的最低检测浓度为0.001—0.003 mg.kg-1.

| Abstract: | A UPLC method of flubendiamide and its metabolite for determination in water,soil,straw,brown rice and rice hull was established.Water samples were purified by extractant ethyl acetate through liquid-liquid extraction.Soil samples were extracted with acetone and purified as water samples.Rice samples were extracted with acetonitrile,and cleaned up by NH2-Carb columns.The average recoveries were 78.2%—104.8%,with variation coefficients of 1.1%—4.4%.The minimum detectable quantity of flubendiamide and its metabolite were 0.004—0.02 ng,and the limits of detection ranged from 0.0008 to 0.0009 mg · L-1 in water,and from 0.001 to 0.003 mg · kg-1 in soil,straw,brown rice and rice hull. |
