中文摘要 | 建立了淫羊霍等药用植物中六六六及滴滴涕异构体残留量的毛细管气相色谱检测方法。样品采用微量化学法进行提取,固相萃取法净化,以不分流方式进样,用HP 5弹性石英毛细管柱程序升温分离样品,微电子捕获检测器检测,外标法计算其质量分数。结果表明,最小检测量为1.4×10-14~1.2×10-12g,加样平均回收率为92.16%~100.59%,相对标准偏差为0.5%~4.2%。该法各项技术指标均满足农药残留检测的要求。; The capillary gas chromatographic method was introduced for the determination of organochlorine pesticide residues in medicinal plants of Epimdium biolba,Cassia nomame, Anthocyanidins, Rhodiola rosea, Safflower and Pueraria Root. The organochlorine pesticides were extracted from samples by micro-chemical technique. Then, the extracts were cleaned up by solid phase extaction, and separated by HP-5 capillary column with micro-electron capture detector. The average recovery was 92.16%~100.59% and RSD was 0.5%~4.2%. The limits of detection were 1.4×10~(-14)~1.2×10~(-12) g. This method is rapid, sensitive, accurate and suitable for analysis of pesticide residues.; "十五"国家科技攻关项目子项目 |
