Abstract	本发明涉及一种锡化羟基磷灰石复合材料的制备方法及其应用，其制备方法采用离子交换法合成的以羟基磷灰石为载体，进行二价锡负载，经过搅拌、洗涤、干燥、冷却后得一种锡化羟基磷灰石复合材料。本发明制备的锡化羟基磷灰石复合材料，能将高毒性的六价铬还原成低毒性的三价铬，同时能够快速去除水中的钴、镍、铜等重金属离子。本发明提供的复合材料可应用于铬污染土壤的修复和治理，以及重金属污染场地地下水中多种重金属离子的去除与净化。
Other Abstract	The invention relates to a preparation method and application of a stannized hydroxyapatite composite material, and the preparation method comprises the following steps: carrying out divalent tin loading by using hydroxyapatite synthesized by an ion exchange method as a carrier, stirring, washing, drying and cooling to obtain the stannized hydroxyapatite composite material. According to the prepared stannized hydroxyapatite composite material, high-toxicity hexavalent chromium can be reduced into low-toxicity trivalent chromium, and meanwhile, heavy metal ions such as cobalt, nickel and copper in water can be rapidly removed. The composite material provided by the invention can be applied to remediation and treatment of chromium-contaminated soil and removal and purification of various heavy metal ions in underground water of a heavy metal contaminated site.
