部分单元素空心阴极灯的发射光谱研究

Study on Emission Spectrum of Some Single Element Hollow Cathode Lamps

报道了13种元素的19支单元素空心阴极灯(HCL)的发射光谱。发现部分元素的空心阴极灯发射线与其他元素的共振线或非共振线存在谱线重叠现象。对产生这一现象的原因作了初步探讨。提出这些单元素灯在理论上可用于多个元素的测定,并且可用作多元素同时测定原子吸收分光光度计的光源。

In this paper, the emission spectra of 13 kinds of elements were determined on 19 single element hollow cathode lamps. The spectral overlap was discovered among emission lines of some elements and resonance lines or non-resonance lines of other elements. The reason for producing this phenomena was discussed initially. The viewpoint that these single element lamps can be used to the multielement determination and as the light sources of simultaneous multi-elements determining atomic absorption spectrophotometer was put forward.
