摘要
本文制定了N_2O-C_2H_2焰原子吸收光谱直接测定Sm-Eu-Gd富集物中Sm、Eu和Gd的分析方法。采用氧化镧溶液作为缓冲剂消除干扰提高灵敏度。此法不需要复杂的分离过程。方法简便、快速、成本低、适合工厂采用。
The analytical method for direct determination of Sm, Eu, Gd in Sm-Eu-Gd concentrationby atomic absorption spectrometry with N_2O-C_2H_1 flame was established in this paper. Thesolution of lanthanum oxide is used as buffer to eliminate the iaterference and to increase thesensitivity. Separation is not necessary. owing to its simplicity, rapidity and cheapnees, themethod is useful to factories.
