深孔电极发射光谱法连测化探样品中铌、锆、镧、钇、铍、锶、钡的方法研究

用３×５×０．５ｍｍ深孔电极增大装样量，用垫热加缓冲层的办法使样品尾烧完全，通过向光谱标准中滴加适量碳酸钠，使之与被测样品中各元素的蒸发行为趋向一致。一次摄谱，连测化探样品中微量铌、锆、钇、铍、镧、锶、钡７种难挥发元素

Analyse Seven elements: Nb Y Be La Sr Zr Ba With Emisson Spectrometry

A method was found; sample amount was increazed with 3×5×0.5mm deep pore eledtrod and dully fired with increasing buffer layer.Evaporate conduct of elements in spectrometry standard was identified with the ones in the analysed sanple by appropriat amount of Na 2co 3 Was put in the standard. Seven umevaporable microelements:Nb,Y,Be,La,Sr,Zr,Ba Ware analysed by a spectroghaph.
