研究了在不同温度下的NaNO3和AgNO3水溶液中Li1.3Ti1.7Al0.3(PO4)3和Na1.3Ti1.7Al0.3(PO4)3离子交换行为. 实验表明Li1.3Ti1.7Al0.3(PO4)3和Na1.3Ti1.7Al0.3(PO4)3均显示出了高选择性与Na＋和Ag＋进行离子交换的特征, 且对Ag＋的选择性高于Na＋. 升高温度可显著提高Ag/Li和Ag/Na的交换反应速度.

关键词: Li1.3Ti1.7Al0.3(PO4)3, Na1.3Ti1.7Al0.3(PO4)3, 离子交换

The ion exchange reaction and behavior for the Li1.3Ti1.7Al0.3(PO4)3 and Na1.3Ti1.7Al0.3(PO4)3 in NaNO3 and AgNO3 solutions were investigated at different temperatures. The experimental results show that the Li1.3Ti1.7Al0.3(PO4)3 and Na1.3Ti1.7Al0.3(PO4)3 have very high ion exchange selectivity to Na＋and Ag＋in NaNO3 and AgNO3 solutions, and the selectivity to Ag＋ is higher than that to Na＋. The Ag/Li and Ag/Na ion exchange reaction rate increased obviously with increasing temperature.

Key words: Li1.3Ti1.7Al0.3(PO4)3, Na1.3Ti1.7Al0.3(PO4)3, ion exchange
