Abstract
A method of determining the Ba content in Si-Al-Ba Alloys by ICP-AES was developed, in which the alloy was dissolved in a mixed acid of HF-HNO_3-HClO_4, and the Ba content was determined using the 233.527 nm peak of Ba. Being simple, quick, precise and accurate in operation, this method has yielded a recovery rate of 99%～100% with samples containing calibrating additions, and in a relative standard deviations of 0.25%～0.56%.
