The technique of the compositional modification by using ion exchange reactions can produce metastable materials with various unique characteristics. In this study, we have synthesized the ion memorized materials by means of the ion exchange, especially K^+ and Br^- ions memorized materials which selectively take up K^+ and Br^- ions in the presence of a large excess of analogous ins, and then have investigated the characteristics on the metastable materials. Consequently ,the outstanding ion selectivity was discovered on modified fluormicas and apaties.1. Two modified fluormicas(NaT and HT)were prepared by substituting Na^+ and H^+ ions for interlayer K^+ ions in taeniolites [KMg_2LiSi_4O_<10>F_2]. The cation exchange selectivities for Na^+, K^+, Mg^<2+>, and Ca^<2+> ions on NaT and HT have been examined. The orders of cation selectivities on NaT and HT were found to be K^+>>Mg^<2+>*Ca^<2+>>Na^+,and NaT and HT took up a regular amount of K^+ ions without depending on the concentrations of Na^+, Mg^<2+>, and Ca^<2+> ions, which coexisted in aqueous solution. From the results, it was concluded that NaT and HT were K^+ ion memorized ion exchanger, and could be utilized in the separation and immobilization of K^+ ions from the system including Na^+, K^+, Mg^<2+>, and Ca^<2+> ions, for example, seawater, body fluid, and so on.2. A modified apatite(PbBr_<2-x>Cl_xAp)was prepared by substituting Br^- for Cl^- ions in lead bromapatite [PbBrAp;Pb_<10>(PO_4)_6Br_2]. The anion exchange selectivities for Br^- ions in the presence of Cl^- ions on PbBr_<2-x>Cl_xAp and PbClAp have been examined. PbBr_<2-x>Cl_xAp selectively took up Br^- ions in spite of depending on the concentration of Br^- ions, while PbClAp scarcely took up Br^- ions. The results suggested that PbBr_<2-x>Cl_xAp exhibited the Br^- ion memorized characteristics, and was useful for the separation and immobilization of Br^- ions.

利用离子交换反应进行成分修饰的技术可以制备出具有各种独特特性的亚稳材料。在本研究中，我们通过离子交换的方法合成了离子存储材料，特别是K~(++)和B~(2+)离子存储材料，在大量类似的InS存在的情况下选择性地吸附K~(++)和B~(2+)离子，并研究了亚稳态材料的特性。结果发现，改性氟云母和磷灰石具有良好的离子选择性。用Na~+和H~+离子取代钙钛矿[KMG_2LiSi_4O_&lt；10&gt；F_2]中的层间K~+离子，制备了两种改性氟云母(NaT和HT)。考察了Na~(++)、K~(++)、Mg~(2+)~(2+)和Ca~(2+)~(2+)在NaT和HT上的阳离子交换选择性。结果表明，NaT和HT的阳离子选择性顺序为K^+&gt；&gt；Mg^&lt；2+&gt；*Ca^&lt；2+&gt；&gt；Na^+，和NAT，HT对K~+离子的选择性与水溶液中共存的Na~+、Mg~(2+)~(2+)和Ca~(2+)的浓度无关。结果表明，NaT和HT是K~(++)离子记忆离子交换剂，可用于海水、体液等体系中Na~(++)、K~(++)、Mg~(2+)~(2+)和Ca~(2+)~(2+)的分离和固定化。用溴磷灰石[PbBrAp；PbAlt；10&gt；(PO4)6Br2]中的Br2-取代Cl2-离子，制备了一种改性磷灰石(PbBrLt；2-x&gt；ClxAp)。本文研究了在PbBr2-x&Gt；ClxAp和PbClAp上存在Cl2-离子的情况下，Br2-离子对阴离子的交换选择性。PbBr2-x&gt；ClxAp选择性地吸附Br^-离子，而PbClAp几乎不吸附Br^-离子。结果表明，PbBr2-x&gt；ClxAp具有对Br2+离子的记忆特性，有利于分离和固定Br2+离子。
