| 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. |
