摘　　要：本文是系列工作的第四部分。利用光栅刻线为 3 60 0条 /mm的顺序扫描高分辨率ICP AES光谱仪研究了铕 (Eu)和钆 (Gd)分别作为基体时对其他 14个稀土元素共 66条“首选分析线”的光谱干扰情况 ,获得了相应的光谱干扰轮廓和其他光谱干扰信息 。The spectral interferences of Eu and Gd(100 μg·mL -1 ,separately)as matrices on the other REEs(1 or 5 μg·mL -1 ) were studied with a high resoultion sequential ICP AES with a grating of 3 600 grooves/mm.Toatlly 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.
