| 摘 要： | 研究了次灵敏线407．8nm原子吸收光谱法测定工业碳酸锶中碳酸锶含量的条件，建立了一种全新的分析方法，即在测定过工业碳酸锶的杂质含量后，用高纯物质配制与被测样品成分一致的工作溶液，与样品溶液比较测定。该方法要求两种溶液的基体；介质；酸度；释放剂尽量一致，并同时使用标准曲线法和直线比较法。该方法准确，简单，快速，同一样品八次测定结果的极差小于0.3％，相对标准标差为0．10％。测定结果与国标方法相吻合。

| Abstract: | This paper studied the conditions of determining the content of industrial strontium carbonate using atomic absorption spectrum of hyposensitive wavelength 407.8nm,established a completely new analytic method,i.e.,after measuring the content of impurities in industrial strontium carbonate,prepare a working solution equal in composition to the sample to be tested with high purity substance,and then make a comparative measurement of the sample solution.This method is accurate,simple,and quick,8 times of same ... |
