英文摘要	A simple, cheap and rugged method was developed for simultaneous deter mination of 6 neonicotinoid residues in soil, including imidacloprid, acetamiprid, thiamethoxam, thiacloprid, clothianidin and nitenpyram. The soil sample was produced by dispersive liquid-liquid micro-extraction (DLLME) after extracted by the mixed solution of acetonitrile and CH2Cl2 (2 1, phi). The analytes were separated by HPLC with Alltima (TM) C-18 column (4. 6 mmX 250 mm, 5 mu m) and detected by PDA at 260 tun. External standard method was used for quantification. The results showed that good linearity was obtained with correlation coefficients between 0. 998 2 and 0. 999 9 in the range of 0. 5 similar to 200 mu g.L-1. The limits of detection (LODs) were in the range between 0. 000 5 and 0. 003 mu g.mL(-1) (S/N=3). The method was validated with five soil samples spiked at three fortification levels (0. 05, 0. 1, 1.0 mg.kg(-1)) and recoveries were in the range of 55. 3%similar to 95. 6% with RSD of 1. 4%similar to 7. 0%. The effect of clean-up was evaluated by UV spectra and demonstrated that the method established is effective. In conclusion, this method is competent for the simultaneous analysis of 6 neonicotinoid residues in soil.
