| 摘 要： | 系统地研究了用空气——乙炔火焰原子吸收光谱分析法测定高纯石英粉中钙的最佳条件，建立了14％的乙醇作为增感剂，在2％盐酸介质中，0．4％ LaCl3溶液作为释放剂，用塞曼火焰原子吸收法测定的可行性方案，探讨了共存元素对钙的干扰及其消除。方法操作简便快速，干扰少，方法相对标准偏差小于3％，适用于日常分析石英粉中的杂质。

| Abstract: | The optimum conditions was systematically studied in the determination of trace calcium in high purity quartz powders by air acetylene flame atomic absorption spectrometry. A feasibility method was established that using 14% alcohol as sensitizing agent and 0.4% LaCl3 as releasing agent, at the medium of 2% hydrogen chloride, Ca was determined by Zeeman flame atomic absorption method. The interference of coexistence elements to Ca and their cancellation were investigated. The operation was simple and fast, and the interference was litter. The relative standard deviation of method was smaller than 3% and could be apply to determine the impurity in the quartz powder. |
