摘　　要：用火焰原子吸收法,测定了氯化锂中Na+、Ca2+、Mg2+三种主要杂质离子的含量。考察了基体锂对三种离子测定结果的影响及各离子相互之间的干扰。各离子的回收率在100.7%～103.5%之间,测定结果的相对偏差为1.0%～4.9%。In this paper,the three dominating impurities of Na^＋ ,K^＋ and Mg^2＋ in homemade lithium chloride were determined by flame atomic adsorption spectroscopy. The working conditions were investigated and the interferences of lithium on determination results of the three ions were also discussed. The recoveries of the method proven to be simple,rapid and exact are between 100.7% - 103.5%. And the RSD of the results is between 1.0%- 4.9%. The determination results are satisfactory.
