摘要
A new strategy for the confinement of iodine has been developed: it consists in incorporating iodate anions (IO3-) into hydroxyapatite (Ca-10(PO4)(6)(OH)(2), HA). The iodate-substituted HA was synthesized by precipitation, and characterized in detail. Its thermal stability and resistance to leaching were then evaluated, revealing promising properties in view of radioactive iodine confinement applications.
