摘　　要：锂离子传导材料Li1.3Ti1.7A l0.3(PO 4)3 是具有NASICON结构的功能材料,与Na+进行离子交换具有选择性高的特性.研究了在不同温度条件下NaCl和LiCl水溶液中Li1.3Ti1.7A l0.3(PO 4)3 上的Na/Li离子交换行为.实验结果表明,升高温度能显著提高Li1.3Ti1.7A l0.3(PO 4)3 的Na/Li交换反应速率,提高LiCl中杂质Na的分离效果.The lithium ion conductor Li1.3Ti1.7Al0.3(PO4)(3) is a NASICON structural functional material, which has very high selectivity of ion exchange for Na+. The effects of temperature on Na/Li ion exchange reaction for the Li1.3Ti1.7Al0.3(PO4)(3) in sodium chloride and lithium chloride solutions were investigated. The experimental results show that the Na/Li ion exchange reaction rate increases obviously for Li1.3Ti1.7Al0.3(PO4)(3) with increasing temperature in the same infiltration time, and the Li1.3Ti1.7Al0.3(PO4)(3) is very effective to separate sodium impurity from lithium chloride solution.
