摘要

我们展示了水热法生长的磷酸氢锆钠（(Na,H)-ZrP）晶体，它具有很高的钙离子选择性。据估计，(Na,H)-ZrP 和 γ 型 ZrP 上 Ca2+ 交换的标准吉布斯自由能分别为 -10.1 和 -4.69 kJ mol-1。(Na,H)-ZrP对Ca2+的高选择性可归因于(Na,H)-ZrP的离子交换位点与Ca2+之间的尺寸匹配。

Na ion-exchanged zirconium phosphate crystal with high calcium ion selectivity†

We demonstrate hydrothermally grown sodium hydrogen zirconium phosphate ((Na,H)–ZrP) crystals exhibiting high calcium ion selectivity. The standard Gibbs free energies for Ca²⁺ exchange on (Na,H)–ZrP and γ-type ZrP were estimated to be −10.1 and −4.69 kJ mol⁻¹, respectively. The high Ca²⁺ selectivity of (Na,H)–ZrP could be attributed to the size matching between the ion exchange site of (Na,H)–ZrP and Ca²⁺.
