| 摘 要： | 采用原子吸收分光光度计对稀土产品中锶进行测定。通过加入Ｌａ＾３＋，Ｋ＾＋溶液，抑制了Ａｌ，Ｓｉ等多种元素的干扰，提高了锶的灵敏度，用标准加入法消除基体效应。在最佳实验条件下，方法的回收率为９４．０％￣１０４．５％。

| Abstract: | In this paper,Sr an impurity in RE products is determined by atomic absorption spectrophotometer,through addition La 3 or K solutions,many elements such as Al,Si et. are inhibited to determining Sr and the sensitivity of Sr is raised,the matrix effect could be removed by standard addition methord.In the optimum condition,recovery ratio of Sr is between 94.0% and 104.5%. |
