摘　　要：建立了一种动态反应池-电感耦合等离子体质谱法测定菊芋中铬、砷、镉和铅4种有害元素的分析方法。利用该方法分析GBW 07604国家杨树叶标准物质,分析结果与标准值一致。实际样品加标回收率为89%~110%。该方法准确、快速,可用于菊芋及其产品中铬、砷、镉和铅4种元素的分析。A method was established to determine chromium,arsenic,cadmium and lead in Jerusalem Artichoke by inductively coupled plasma mass spectrometry with dynamic reaction cell. The developed method was applied to analyze GBW 07604 national standard reference material of poplar leaves and the found values were agreeable to those certified. In real sample analysis,the recoveries were 89% ～ 110%. This method is correct and fast and can be utilized to the above four harmful elements analysis in Jerusalem Artichoke and its products.
