摘要
应用ICP-AES法测定复合脱氧剂硅铝钙钡合金中的钙、铝元素,在钙铝元素的谱线中选择合适的谱线做分析线,达到钙铝的同时测定。用标准加入法做回收试验,测得回收率在98.9%-99.3%,测定值的相对标准偏差为0.41%-0.42%。试验证明：该分析方法简便、快捷,实现了硅铝钙钡合金中钙、铝元素的同时在线分析,可应用于日常分析实验工作。
With suitable spectrum line as analysis line,the calcium and aluminium element in complex deoxidizer Si-Al-Ca-B alloy can be determined at one time with ICP-AES method.Recover test is done with standard-adding method,and recovery is determined as 98.9 to 99.3 percent,the relative standard error of determined value 0.41 to 0.42 percent.It is proved through the test that the method is simple and fast.
