摘要
提出了同时测定稀土——铝合金中La,Ce的分光光度法。采用混合掩蔽剂SSA+EDTA-Zn+EDTA联合掩蔽大量基体及工La,Ce以外的稀土元素。改变掩蔽剂用量调节体系化学平衡,以ASApA显色成功地进行了La,Ce同时测定。此法用于重稀土铝合金样品分析,得到了满意的结果。
A new method for simultaneous determination of lanthanum and cerium in the aluminium alloy with p-acetylarsenazo by spectrophotometry was proposed. The other rare earths and aluminium base, except lanthanum and cerium, are masked with zinc-ethylenediaminetetracetic acid, ethylenediaminetetracetic acid and sulfosalicylic acid. This method has been successfully applied to the analysis of lanthanum and cerium in synthetic standard reference sample of aluminium alloy, and results obtained are in good agreement with the standard values.
