Thermodynamic Analysis of Effective Na/ K Removal from Metallic Lithium by Molten Salt Extraction

熔盐萃取法深度除去金属锂中钠和钾的热力学分析

It is conventionally difficult to obtain metallic lithium with ultra low Na/ K content, to which the molten salt extraction is therefore suggested as a pioneer process to remove Na/ K and relevant experiments.

针对传统锂工业中很难得到低钠和钾的金属锂，首次提出了溶盐萃取法，并进行了萃取过程的热力学分析和探索性实验研究。

Furthermore, the experimental results also revealed that the molten salt extraction an effective way to remove Na and K, especially the K from metallic lithium, which is basically in conformity to the thermodynamic analysis.

探索性实验结果表明，熔盐萃取法可除去金属锂中的钠和钾，尤其是除钾效果比较明显，这与热力学分析结果基本吻合。
