原子吸收光谱同时测定多元素的研究

本文着重从提高原子吸收光谱分析的效率出发,利用等离子体光源和光谱仪以替代目前原子吸收光谱分析所用的空心阴极灯和单色器系统,对多种元素进行同时测定。选用了Ca、Mg、Fe、Mn等四个元素进行实验,结果良好。此外,对这种方法的特点以及在实际工作中的应用等方面也作了简要叙述。

RESEARCH ON AAS FOR SIMULTANEOUS MULTI-ELEMENTS DETERMINATION

In order to raise measuring efficiency in AAS, we used ICP source and spectrometer to replace hollow cathod lamp and monochromator, separately. The latter are widely used in AAS at present. We selected Ga, Mg, Fe and Mn for demonstrating efficiency of this method. These four elements can be determined simultaneously. Experimental results were satisfied. The is a brief discussion about some characteristics of this method and it's application in practice in this paper.
