提出了一种快速测定硅铝钡钙合金中的铝、钡、钙的电感耦合等离子体原子发射光谱法（ ICP-AES）。样品用硝酸、氢氟酸溶解，高氯酸冒烟后补加硝酸溶解，选择396.152 nm、233.527 nm和184.006 nm波长的谱线分别作为铝、钡和钙的分析线，利用国家标准样品建立的校准曲线，在优化仪器工作参数条件下，对国家标准样品的进行测定，铝、钡、钙三种元素的测定值与认定值基本一致，相对标准偏差分别为0.59％、0.51％和1.36％，相对误差＜3％。

The method of determining the content of Al , Ba and Ca in Si-Al-Ba-Ca alloy quickly by inductively coupled plasma -atomic emission spectrometry ( ICP-AES ) was issued , the sample was dissolved by nitric acid and hydrofluoric acid and then perchloric acid was added to make smoke rise , adding nitric acid again to dissolve sample.By selecting 396.152 nm, 233.527 nm and 184.006 nm as Al, Ba and Ca analysis spectral line respectively , using the standard samples , the calibration curves and optimization of instrument work parameter were established.Under the selected experimental conditions and the selected optimal instrumental parameters , a group of standard samples was determined.The found results of Al , Ba and Ca were consistent with the certified values.The relative standard deviations ( RSD) were 0.59%for Al, 0.51%for Ba and 1.36%for Ca, and the relative error was less than 3%.
