摘要
采用强碱分离-EDTA滴定法测定了硅铝钡球中的铝含量。结果表明,该方法的精密度较高,解决了制取试样困难,分析时溶解不完全等问题,操作简单方便,能够及时提供准确可靠的数据,满足了炼钢生产要求。
The content of aluminum in silicon aluminum barium ball was determined with alkali separation- EDTA titration method. Results indicated that with high precision, this method removed the difficulty in sample taking and preparation and solved the problem of incomplete dissolution. Easy and convenient, it could provide reliable data accurately and timely, meeting the requirement by steel-making production.
