稀土单氧化物发射光谱法的研究I.混合稀土浓集物中钐的双波长测定
Studies on Monoxide Emission Spectrometry of Rare Earth Elements I. Determination of Samarium in the Rare Earth Mixture Concentrates by Dual Wavelength Method
【摘要】 报道了空气乙炔火焰中SmO蒸气的发射光谱行为,试验了La、Nd、Eu、Y对SmO发射强度增强作用,在大量La存在下,SmO的发射强度与其浓度成正比关系。用大量La作增感剂和干扰抑制剂,借助双波长测定法克服光谱干扰,实现了直接测定高Y混合稀土浓集物中的Sm,方法准确,快速
【Abstract】 The paper focuses on the study of the sensitization of La, Nd, Eu and Y on the determination of Sm by air acetylence flame monoxide vapor emission spectrometry. Dual wavelength method was used to eliminate spectral interference. A new method has been established for the direct determination of Sm in the high Y rare earth mixture concentrates, using La as the enhancing agent and interference inhibitor.
