摘要
建立了硅铝钡合金中铝量的快速测定法。试样经酸溶解后,在一定条件下使铝与酒石酸钠的络合物被氟化钠破坏,定量地游离出碱,然后以酚酞作指示剂用硝酸标液滴定碱,进而计算出铝量。
In this paper,a study for high speed determination of aluminum in Si-Al-Ba alloy has been described.The samples are dissolved by a mixed solution of HNO3-HF.This method is simple and rapid,and has been used for the determination of aluminum in Si-Al-Ba alloy with satisfactory result.
