| 摘 要： | 油菜籽和土壤中残留的草除灵，以丙酮提取，经SPE—F10risil柱层析净化；油菜植株中残留的草除灵，以丙酮、0．01％磷酸水溶液提取，二氯甲烷液一液分配后SPE—Florisil柱层析净化。高效液相色谱（紫外检测器）测定，外标法定量。结果表明，草除灵平均添加回收率超过88．5％，相对标准偏差〈8．0％，方法最小检出量1．0×10^-10g，最低检出浓度0．01mg／kg。

| Abstract: | Benazolin in rapeseed and soil was extracted by acetone and cleaned by SPE-Florisil.Benazolin in rape pant was extracted with acetone with 0.5%phosphoric acid aqueous solution,liquid-liquid partition by dichloromethane and cleaned by SPE-Florisil.The above residue Benazolin was checked by HPLC with UV detection 200nm,based on an external standard calibration curve.The results showed that: the average reclaim ratio was above 88.5%,the relative standard deviation was under 8.0%,the minimum detectable level was 1.0×10-10g,and the minimum residue was 0.01mg/kg,which was accord with the residue analysis request. |
