标准加入原子吸收分光光度法测定高纯稀土产品中的微量钙

The determination of trace calcium in highly purity RE samples by the atomic absorption spectrophotometry combined with standard addition method

针对高纯稀土产品中微量钙的测定进行了试验。通过试验 ,确定了仪器最佳工作条件 ,用盐酸和硝酸分解试样 ,并采用标准加入原子吸收分光光度法测定 ,满足了产品分析质量要求。

The optimal work condition of instrument and experiment are selected through a thorough study on the determination of trace calcium. The samples dissolved in hydrochloric acid and nitric acid,the satisfactory results of atomic absorption spectrophotometry combined with standard addition method is employed to determine trace calcium in highly purity RE samples.
