用改进的全耗型燃烧器火焰光度法测定锂的研究

Study on Flame Spectrophotometric Determination of Lithium by Improve Total Consumption Burner

本文报导了用改进的贝克曼燃器火焰分光光度法测定锂的研究。改进后的燃烧器可采用液化石油气——氧气。直接测定铋中锂的下限为50μg/g,分析结果同发射光谱法很好地符合。

In this paper, improve total consumption burner as spectrophotometer was been reported. Lithium in bismuth was determined with flame spectropho- tometry. The burner applies to liquefied petroleum gas-oxygen. The lower limit of lithium is 50μg/g. The analytical result of Li in bismuth are perfectly agrees with that of spectrochemical analysis.
