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+.
期刊介绍：
Dalton Transactions is a journal for all areas of inorganic chemistry, which encompasses the organometallic, bioinorganic and materials chemistry of the elements, with applications including synthesis, catalysis, energy conversion/storage, electrical devices and medicine. Dalton Transactions welcomes high-quality, original submissions in all of these areas and more, where the advancement of knowledge in inorganic chemistry is significant.
