本文介绍了用分光光度法测定铝合金中微量轻稀土的快速分析方法,大最铝的存在不干扰测定、与其它方法比较,本法结果是令人满意的。本法也适用于其它各类合金中微量轻稀土。
This paper introduces the rapid spectrophotometric method for the determination of trace light rare earths in aluminum alloys. The presence of a large amount of aluminum does not interfere with the determination. Compared with other methods, this method is satisfactory. This Law also applies to other types of light trace rare earth alloys.
