摘　　要：采用乙腈法提取残留物抑食肼,用氧化铝层析柱净化,并用液相色谱法测定了稻杆中抑食肼的残留量。结果表明,液相色谱法在稻杆中的最低检出浓度为0.02mg/kg,回收率均在84%～104%,变异系数均在0.095～0.140,能满足农药残留分析的要求。The RH-5849 residue in rice stem was detected by using the HPLC. The residue was extracted with acetonitrile, followed by cleanup with an alumina column. The minimum for detection of RH-5849 was 0.02 mg/kg, the recovery rate ranged from 84% to 104%, and the variance coefficient was 0.095-0.140. These results showed that the HPLC method accords with the demand for detection of pesticide residues.
