还原气化-原子荧光光谱法快速测定绿色食品基地土壤中的砷与汞

Using Reduction Gasification AFS Method Quickly Measure of Arsenic and Mercury in the Soil of Organic Food Base

应用还原气化 原子荧光光谱法 ,使待测元素与基体自动分离、富集 ,测定绿色食品基地土壤中的As、Hg .经对国家级土壤标准物质进行分析证明 ,该方法具有快速、准确、灵敏度高等优点 ,用于绿色食品基地的审评检测 。

With the adopted method of reduction gasificatiom AFS, the As?Hg elements of the soil of organic food base can be automatically seperated accumulated and mensurated. The analytical results with the standard material of national level soil indicate that the proposed method has the advantages of quickness, accuracy and high sensitivity. It is very useful to assess and to detect organic food base.
