本文报道了以ＨＮＯ３ － ＨＣｌＯ４ 混酸消化、Ｈ２ＳＯ４ － ＫＩ－ Ｔｅ（ Ⅳ） 体系极谱法测定中药川附子中的砷。该方法使样品消化过程的砷损失大为减少并简化了分析过程。样品中砷含量在０－２ ～０－６μｇ·ｇ－ １ ，回收率８４ ％ ～１０８ ％ 。
This paper reports the determination of arsenic in traditional Chinese medicine Chuanxiong by H2SO4 - KI-Te (IV) system polarography with HNO3 - HClO4 mixed acid digestion. This method greatly reduces arsenic loss during sample digestion and simplifies the analysis process. The arsenic content in the sample ranged from 0-2 to 0-6μg·g-1, and the recovery rate was 84% to 108%.
