Abstract
The interaction between polyacrylate ions and hydroxyapatite was examined using extraction techniques and infra-red spectroscopy. These studies have shown that polyacrylate ions become irreversibly attached to the surface of hydroxyapatite by displacing existing phosphate ions. The mechanism is not one of simple ion exchange, since calcium ions are displaced by the phosphate ions.
摘要
采用萃取技术和红外光谱法研究了聚丙烯酸酯离子与羟基磷灰石之间的相互作用。这些研究表明，聚丙烯酸酯离子通过取代现有的磷酸根离子而不可逆地附着在羟基磷灰石表面。该机制并非简单的离子交换，因为钙离子被磷酸根离子取代。
