Abstract

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⁺.

具有高钙离子选择性的 Na 离子交换磷酸锆晶体

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。
