| 摘 要： | 本文就火焰原子吸收法测定工业氧化镁中杂质元素钙，铁和锰的条件进行了试验，对基体元素的影响和消除方法进行了探索。所建立的方法应用于工业氧化镁产品中的铁，钙和锰的分析，结果与国家标准方法分析结果相比较，经统计检验，两者无显著性差异。相对标准偏差钙为１．４１％，铁为３．２０％，锰为０．９６％。方法简便，快速，准确，可用于工业氧化镁产品的质量检验。

| Abstract: | The condition of simultaneous determination of the tripurity Ca,Fe and Mn in magnesin is stud-ied in this paper. The influence of matris and the methed of eliminating it are aiso studied. The statis-tical result shows that this method is almost as accurate as national standard analytic method. The rel-ative standard dehation is 1. 41 % for Ca, 3, 20% for Fe, 0. 96% for Mn. This method is simple,rapid and accurate, and can be used to inspect the quality of magnesta. |
