摘要: 采用高效液相色谱-二极管阵列检测器对蔬菜中噻虫啉残留量进行测定。样品用乙腈提取后,经Florisil固相萃取小柱净化,用C8液相色谱柱、二极管阵列检测器,对蔬菜中噻虫啉残留量的测定可取得满意的结果。该方法样品平均加标回收率为81.8%~97.5%,相对标准偏差为1.36%~7.80%;蔬菜中噻虫啉检出下限为0.02mg/kg。

Abstract: A method to determine thiacloprid residue in vegetables was developed using high performance liquid chromatography with diode array detector (HPLC-DAD). Samples were extracted by acetonitrile, cleaned up on florisil SPE column, separated on C8 liquid chromatography columns and detected with DAD. The average recoveries of thiacloprid in three species of vegetables at three spike levels were 81.8%-97.5% with a relative standard deviation of 1.36%-7.80% (n = 6). The detection limit of the method was 0.02 mg/kg.

Key words: vegetables, thiacloprid, residue, high performance liquid chromatography, DAD
