Lithium is chemically active and prone to react with residual gases in the atmosphere, which should be taken into account for the application of lithium in fusion facility. In the present study, effect of N₂ on the release temperature of D₂ in liquid lithium was investigated. Absorption experiments were performed at 400 °C by exposing lithium in N₂ or D₂ atmosphere. Thermal desorption spectrometry (TDS) was used to measure the desorption temperature of Li samples. New D₂ peaks which are below the decomposition temperature of LiD but higher than that of D₂ dissolved in liquid lithium are observed in Li samples that have absorbed both D₂ and N₂ and the desorption temperature of which varies according to the ratio of N₂ and D₂. Although the mechanism of this reaction is not clear, these results highlight the importance of monitoring the impurity content of liquid lithium and the potential impact on tritium extraction when lithium is applied in fusion facilities.

锂具有化学活性，容易与大气中的残余气体发生反应，锂在聚变装置中的应用应考虑到这一点。在本研究中，研究了 N ₂对液态锂中 D ₂释放温度的影响。通过将锂暴露在 N ₂或 D ₂气氛中，在 400 °C 下进行吸收实验。热脱附光谱法 (TDS) 用于测量锂样品的脱附温度。在吸收了 D ₂和 N _{2 的}Li 样品中观察到低于 LiD 分解温度但高于溶解在液态锂中的 D _{2 的}新 D ₂峰其解吸温度根据N ₂和D ₂的比例而变化。尽管该反应的机制尚不清楚，但这些结果强调了监测液态锂杂质含量的重要性以及在聚变设施中应用锂时对氚提取的潜在影响。
