摘要：

The spectral interferences of Eu and Gd(100 mu g.mL(-1), separately) as matrices on the other REEs(1 or 5 mu g.mL(-1)) were studied with a high resolution sequential ICP-AES with a grating of 3 600 grooves/mm. Totally 66 prominent lines of 14 REEs were selected as the analytical lines for the spectral interference studies. The overlapping profiles of analytical lines and interference lines were obtained by scanning four solutions(blank, analyte, Eu matrix, and Gd matrix, individually) within the selected wavelength windows (0.2 nm for each analytical line). Some new emission lines of Eu and Gd were observed. The obtained information of spectral interferences would be very useful for the selection of the best analytical lines for the determination of REEs in the other REEs matrices.
