摘要
On the basis of investigated enhancement effect of La, Nd, Eu, and Y on Sm determination with monoxide molecular emission spectrometry, La was selected as enhancement agent and chemical interference inhibitor. In the presence of La, dual wavelength mothod was introduced to eliminate the spectral interference on Sm by other elements. A new method was established to determine samarium in high yttrium rare earth samples with satisfactory results.
