摘　　要：羟基磷灰石(HA)吸附能力受酸碱度、其它离子浓度等外界因素的影响,对HA表面改性处理能在一定程度上改变HA表面电性结构,从而改善吸附性能。动力学上多因素作用影响HA吸附速度或改变具体的吸附行为。通过总结HA对无机物、金属及有机物的作用条件、反应过程及吸附机理发现:人们还没有找到一个普遍的理论模型来解释HA与其它材料发生吸附作用的过程,目前对HA表面吸附性能的研究还停留在具体零碎材料的相互作用上。在HA表面嫁接有用的作用基团或物质,通过改变HA表面部分结构以改善吸附性能成为目前和今后一段时间内HA吸附性能研究的重点之一。Adsorption ability of hydroxyapatite（HA） is influenced by many factors like pH value, other ions and so on. Microstructure on the surface of HA with charge is coated by modification methods, and velocity and the specific process of HA adsorption to other materials are restricted by many uncertain factors. On the basis of summary on HA adsorption of metal, inorganic and polymers, it＇s found that the current study on HA adsorption reaction to oth- er simple material remains in the intereaction of concrete scrap materials and there＇ s no universal model in theory to explain the adsorption process between HA and other materials. Surface modification of HA in accordance with practical requirement is one of main development trend in recent future.
