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 method of matrix matching and ICP-AES were used to determine the ten trace elements in high-purity tin at the same time. The results showed that the recovery rate was 93-6% -104-6% and the RSD was ≤4-4% The method is simple, rapid and accurate and is a better method for the determination of trace impurities in high purity tin.
