| 摘 要： | 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.

| Abstract: | The ion exchange reaction and behavior for the Li_(1.3)Ti_(1.7)Al_(0.3)(PO_4)_3 and Na_(1.3)Ti_(1.7)Al_(0.3) (PO_4)_3 in NaNO_3 and AgNO_3 solutions were investigated at different temperatures. The experimental results show that the Li_(1.3)Ti_(1.7)Al_(0.3)(PO_4)_3 and Na_(1.3)Ti_(1.7)Al_(0.3)(PO_4)_3 have very high ion exchange selectivity to Na+and Ag+in NaNO_3 and AgNO_3 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. |
