| The Ion Exchange Behavior of Na/Li and Ag/Li for LiZr2(PO4)3 |
|
| 摘要: 研究了LiZr2(PO4)3在水溶液中的Na/Li和Ag/Li离子交换行为。结果表明，LiZr2(PO4)3对Na+和Ag+离子均具有很高的选择性，且对Ag+的选择性高于Na+。LiZr2(PO4)3与Ag+的离子交换反应是通过形成固溶体的形式进行的,而与Na+的离子交换反应则是通过置换进行的。温度升高有利于提高LiZr2(PO4)3上Na/Li 和Ag/Li的离子交换反应速度。 |

| Abstract: The ion exchange behavior of Na/Li and Ag/Li for LiZr2(PO4)3 in solution was studied. The results show that LiZr2(PO4)3 has very high ion exchange selectivity to Na+ and Ag+ in solution, and the selectivity to Ag+ is higher than that to Na+. In the reaction mechanism aspect, the ion exchange reaction LiZr2(PO4)3 towards Ag+ is through the formation of solid solution, and towards Na+ is carried out through the replacement. The Na/Li and Ag/Li ion exchange reaction rate increases obviously for LiZr2(PO4)3 with increasing temperature. |
