摘　　要：将样品转化成氧化物按一定比例与载体混合,直流电弧阳极激发,凹面光栅分光,选择特征谱线由光电倍增管接收光能量,用原子发射光谱法检测铌中Fe、Cr、Ni等18种元素。The sample was oxidized and then mixed with the buffer in proportion. Fe,Cr,Ni and other 18 kinds elements were determined by atomic emission spectrum using dc arc for excitation, concave grafting for dispersion, and choosing the characteristic spectra for receiving energy by photomultilier.
