| Abstract: | 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. |
