| 摘 要： | 采用自制封闭溶样器对铝土矿进行处理，在盐酸介质中，用火焰原子吸收光谱仪于波长598．2nm处，测定Na2O的吸光度；于波长766．7nm处，测定K2O的吸光度。此方法适合对铝土矿中钾、钠的测定，具有选择性好，操作简便、快速，测定结果准确等优点。

| Abstract: | Adopting self-made close digester to process bauxite, the absorbance of Na2O has been determined at the wavelength of 598.2nm by the application of flame atomic absorption spectrometry in HCl medium; besides, the absorbance of K2O has also been determined at the wavelength of 766.7nm through the same method. This method is applicable for the determination of K, Na in bauxite with its advantages of good selectivity, simple and fast operation, as well as accurate testing results etc. |
