| Abstract: | In this paper,the three dominating impurities of Na+,K+ and Mg2+ 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. |
