摘    要:利用还原气化的非色散型装置,以湿法消解的方式,对中药甘草中的痕量汞进行了原子荧光测定。研究了影响测定结果的条件,比较了两种玻璃仪器的洗涤方式,并以工作曲线法和加入作图法对照,试验回收率在86.9%-110.8%,误差<13.1%,得出了满意的分析结果。

关 键 词:  甘草  冷原子荧光法  痕量分析  中药分析

Abstract:By applying the nondispersive apparatus with reduction and gasification,and the wet dissolving method,the trace mercury in liquorice is determined by cold atomic fluorometry.We studied the conditions that can affect the determined results.We compared two methods for cleaning the glass ware,and contrasted the working curve method with addition poltting method.We also studied the applicability of this experimental method.The recovery is 86 9%-110 8%.and the error is less than 13 1%.It proves the method is efficient and satisfactory.
Keywords:Trace mercury    Cold atomic fluorometry    Chinese tradition medicine    Liquorice
