| 摘 要： | 提出了毛细管气相色谱法测定"三九胃泰"中20种有机氯残留量的方法。样品经正己烷提取,所得提取液经硫酸磺化。采用DB-1701P色谱柱(30m×0.25mm,0.5μm),在100℃～250℃温度区间采用程序升温方式进行分离,用电子捕获检测器测定。20种有机氯农药的检出限(3S/N)均为10μg·kg-1。用标准加入法测得回收率在70.2%～117%之间,相对标准偏差(n=6)在1.0%～1.8%之间。

| Abstract: | GC was applied to the determination of residual amounts of 20 organochlorine pesticides(OCP′s) in medicine "Sanjiuweitai".The sample was extracted with n-hexane,and the extract was sulphonated with H2SO4.DB-1701P(30 m×0.25 mm,0.5 μm) chromatographic column was used for separation in the temperature range from 100 ℃ to 250 ℃ with programmed temperature elevation,and ECD was adopted in the determination.Values of detection limits(3S/N) for the 20 OCP′s were same to be 10 μg·kg-1.Recovery of the method was tested,giving values of recovery ranged from 70.2%-117% and RSD′s(n=6) ranged from 1.0%-1.8%. |
