ICP-AES同时测定高纯锡中十种微量杂质元素的研究

Tests of ICP-AES on Simultaneous Determination of Ten Trace Elements in High Grade Metal Tin

研究了用基体匹配法和ICP- AES同时直接测定高纯锡中十种微量杂质元素, 研究结果表明该方法回收率93-6 % ～104-6% , 分析精密度RSD% ≤4-4 % ; 该方法简便、迅速、准确是测定高纯锡中多种微量杂质元素的一种较好的分析方法。

The basis match method and ICP-AES are employed for simultaneous determination of ten different trace elements in a high grade metal tin.Testing results show that recovery figures range from 93 6% to 104 1%,and accuracy of RSD% is below 4 4%.This method gives simple,fast and accurent measurement of trace elements in high grade metal tin.
