| 摘 要： | 方法]葡萄样品中的氯吡脲使用含1％乙酸的乙腈提取,N-丙基乙二胺(PSA)吸附剂净化,高效液相色谱-紫外检测器(HPLC-UV)检测;使用所建方法测定了氯毗脲在北京、杭州两地葡萄上的消解动态.结果]氯吡脲的最低检出限为0.003 mg/kg,在葡萄中的添加回收率为95％～104％,变异系数为1.0％～1.8％;在北京和杭州两地,氯吡脲在葡萄上的半衰期分别为11.6、23.1 d.结论]氯吡脲在葡萄中半衰期比在其他基质中更长.

| Abstract: | Methods] Forchlorfenuron in grape samples was extracted with acetronitrile containing acetic acid 1%,cleaned up by PSA adsorbent and detected by HPLC with UV detector.Residue dynamics in grape were studied by this method in Beijing and Hangzhou.Results] The results showed that the limit of detection of forcholorfenuron was 0.003 mg/kg and the recoveries ranged from 95 to 104% with coefficient of variation 1.0-1.8%.The halflives of forcholorfenuron were 11.6 and 23.1 d in Beijing and Hangzhou,respectively.... |
