锂铷铯在空气-乙炔火焰中相互干扰的研究

A Research on the Mutual Interference of Li,Rb and Cs in Air acetylene Flame

阐述了锂铷铯在空气 -乙炔火焰中相互干扰的研究,原子吸收光谱法和火焰光度法测定锂铷铯的灵敏度相近,但碱金属元素熔点低 ,其空心阴极灯稳定性和使用寿命较差 ,故火焰光度法仍被广泛应用。

This paper describe the research on the mutual interference of Li,Rb,Cs in air acetylene flame.It wasconcluded that the flame photometry gave the same results as the atomic absorption spectrophotometry for determming Li,Rb and Cs.Because of the low melting point of alkali metal elements,the lower stability in use and the shorter service life of hollow cathode lamp for alkali metal elements,the flame photometry still is widely used for the determining these elements of Li,Rb and Cs etc.
