摘要 毒鼠强是一种剧毒速效灭鼠药,用这种鼠药拌粮食做成的毒饵在不少地方使用,因投毒、误服造成多起中毒事故。毒饵中鼠药成分的分析鉴定对于中毒病人的诊断与治疗都具有实际意义。所建方法对样品的预处理简单,回收率在86%以上。该方法已用于与两次中毒事故有关的毒饵中鼠药的测定,有助于中毒病人的诊断与治疗。另外,还提出了测定毒饵中鼠药回收率的简易方法。 A simple and rapid gas chromatographic method was established for the determi- nation of tetramine (a highly toxic rodenticide) in rodenticide bait of grains such as rice, corn and wheat. The method involved acetone extraction of the intact (not ground) bait grains and analysis of the extracts by gas chromatography with flame ionization detection (GC-FID). With this method, bait samples from two poisoning accidents were analyzed and the toxicants were thus de- termined. Furthermore, a simple method for the evaluation of recovery was proposed and the re- covery of tetramine extracted from several kinds of grain baits was determined to be above 86%.
