摘　　要：用盐酸溶解铝-钪中间合金试样,在一定酸度范围内,以二甲酚橙为指示剂,用乙二胺四乙酸二钠标准溶液滴定,测量铝-钪中间合金中的钪含量。结果表明,该方法测量准确性好,所用试剂、仪器较少,步骤比较简单,适宜用来测定铝-钪中间合金中的钪含量。Samples of AI-Sc master alloy were dissolved by HC1 and titrated by EDTA standard solution with XO as an indicator in certain acidity, to measure Sc content in A1-Sc master alloy. The results showed that this method was more accurate and used comparatively fewer reagent, instruments and steps. As a result, it is suitable to measure Sc content in A1-Sc master alloy.
