本文介绍了电解预浓缩技术的基本装置和各种工作电极材料,重点评述钨丝工作电极在火焰和无火焰原子吸收分析中的应用及其利弊,指出采用电解后的钨丝直接作原子化器可以弥补仪器设备的不足。最后表列出该技术在原子吸收分析中的应用现状。
This paper introduces the basic equipment and various working electrode materials for electrolytic preconcentration. The application of tungsten working electrode in flame and non-flame atomic absorption spectrometry is reviewed, and its advantages and disadvantages are pointed out. It is pointed out that the electrolysis of tungsten wire directly as a atomizer Can make up for the lack of equipment. The final table lists the technology in the application of atomic absorption analysis of the status quo.
