研究了LiZr_2(PO_4)_3在水溶液中的Na/Li和Ag/Li离子交换行为.结果表明,LiZr_2(PO_4)_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+.LiZr_2(PO_4)_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LiZr_2(PO_4)_3上Na/Li和Ag/Li的离子交换反应速度.

The ion exchange behavior of Na/Li and Ag/Li for LiZr_2(PO_4)_3 in solution was studied. The results show that LiZr_2(PO_4)_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 LiZr_2(PO_4)_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(PO_4)_3 with increasing temperature.
