| 摘 要： | 建立使用高通量(RRHT)色谱柱的高效液相色谱法同时测定大米中呋虫胺、噻虫胺、吡虫啉、吡虫清四种烟碱农药残留量的方法。样品用乙腈提取，采用ENVI-Florisil和Carb复合固相萃取柱萃取净化，液相色谱高通量RRHT色谱柱，258nm紫外测定，外标法定量。检测过程快速准确，2.5min时4种农药可完全分离。样品中加标回收率为75.5%～96.0%，相对标准偏差为0.49%～4.36%，最低检出限达到0.004mg/kg。峰面积与标准溶液质量浓度在0.1～1.0mg/L范围内呈良好的线性关系，线性回归系数大于0.9996。

| Abstract: | A reverse phase high performance liquid chromatography(RP-HPLC) method has been developed for determining dinotefuran,clothianidin,imidacloprid and acetamiprid residues in rice.Neonicotinoid residues were extracted from the sample by acetonitrile,and then cleaned up with ENVI-Florisil and carb SPE tube.The HPLC detection was performed using a DAD detector in the external standard mode.Results indicated that average recovery rates in spiked samples were in the range of 75.5%-96.0%,the relative standard devia... |
