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。

Detection of RH-5849 Residues in Rice and Soil |
| |
Abstract: | 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. |
