ICP—AES测定河流沉积物、生物样品中的微量元素消化方法的研究

Study on Determination of Trace Elements in River Base Soil and Biological Sample by ICP-AES Using Different Acid System

用ICP—AES法测定河流沉积物、生物样品中的微量元素,对处理样品不同的消解液体系进行比较试验。结果表明,用王水—高氯酸—氢氟酸消解液,能使样品得到最完全、最充分的分解,回收率在96.4％～104.6％之间,变异系数在3.0％～0.7％之间。方法准确、灵敏、快速。

A method for determination of trace elements in river base soil and biological sample by ICP-AES is developed . The results of using different acid systems are compared. The method is accurate, simple and rapid.
