采用两种不同的分解方法处理渣驯样品,用ICP-OES法测定了样品中Al、Ba、Ca、Fe、K、Mg、Mn、Ni、Sr元素的含量,并进行比较。结果表明,两种不同的分解方法所测定的金属元素含量基本相一致,相对误差都小于5%。说明两种分解方法所建立的分析方法都能准确、快速测定Al、Ba、Ca等9种金属元素,是值得推荐的有效测定方法。
The slag samples were processed by two different decomposition methods. The contents of Al, Ba, Ca, Fe, K, Mg, Mn, Ni and Sr in the samples were determined by ICP-OES and compared. The results show that the content of metal elements determined by the two different decomposition methods are basically the same, the relative errors are less than 5%. It is indicated that the analytical methods established by the two decomposition methods can accurately and rapidly determine nine kinds of metal elements such as Al, Ba and Ca, and are worthy of recommending and effective measurement methods.
