金属铝中杂质元素的测定及其基体影响的研讨

Matrix Effect and Determination of Impurity Elements in Aluminium

提出了一种能同时测定金属铝中杂质元素Ｃｕ、Ｍｎ、Ｍｇ、Ｚｎ、Ｃｒ、Ｎｉ、Ｖ、Ｔｉ、Ｆｅ、Ｓ的ＩＣＰ－ＡＥＳ分析方法，实验考察了金属铝基体、共存元素、不同溶剂等因素对分析元素测试结果的影响，选择了仪器最佳工作条件。结果表明，当金属铝基体的纯度为９６．００％－９９．９０％时，分析元素的回收率在９５％－１０５．０％之间。相对标准偏差ＲＳＤ均小于０．５％。在金属铝进出口商品检验中已获得满意的结果。

In this paper,matrix effect and determination of Cu,Mn,Mg,Zn,Cr,V,Ti,Fe,Si,Ni,in aluminium is studied by ICP-AES.The best operating parameter is choosed.Results obtained for determination of every elements is aluminium are satisfactory.The RSD is under 0.5% and the recovery is about 96% 99.9%.
