原子吸收分光光度法测定炮制朱砂中可溶性汞含量

本文采用原子吸收分光光度计测定炮制朱砂在人工肠液和人工胃液中可溶性汞的含量。本方法灵敏度高，重出性好，平均回收率为１０２．２７％（ｎ＝６），ＲＳＤ＝３．１９％。应用本方法对贵州，湖南和北京等厂家及医院所使用的朱砂进行了测定，结果表明：朱砂中的中溶性汞盐主要是在人工胃液中溶解，在人工肠液中溶解极少。朱砂炮制方法不同。可溶性汞盐的含量也不同，球磨法高，水飞法低。

The Research on the Content of Dissoluble Mercury Saltsin Processed Cinnabar Determined by Atomic Absorption Spectrometry

This paper will discuss th content of dissoluble mercury salt(in processed cinnabar) in artificial intestinal juice and gastric juice determined with atomic absorption spectrometer,This method has high sensitivity, good reappearance and the average reclamation rate is 102.27%(n=6),RSD=3.19%.It has been applied to detect the processed cinnabar used by several factories and hospitals of Guizhou, Hunan and Beijing,ect.The result shows that the dissoluble mercury salt in processed cinnabar dissolves mainly in the artificial gastric juice while very little in the artificial intestinal juice. And it also shows that the ways of processing cinnabar are different,thus,the content of the dissoluble mercury salt are different.And we can get dissoluble mercury salt with high content with the ball mill method while with the refining drugs with water we can get it with low content,
