羟基磷灰石(Hydroxyapatite,HA)独特的化学组成和晶体结构,使其具有良好而广泛的吸附性能,作为一种新型的环境友好材料和高效的吸附剂,其应用领域日益扩展。HA针对不同种类的目标物质其吸附机理不尽相同,因此对其制备方法也有不同要求。然而,相关的研究却鲜有报道。通过分析HA吸附重金属离子和蛋白质的差异,讨论了其吸附机理的异同和对制备方法的不同要求,并进一步分析不同吸附机理与制备方法之间的关系,展望了今后的研究方向。
Due to its special composition and crystal structure, hydroxyaoatite exhibits excellent adsorption property. As a new kind of environmentally friendly material and high efficient adsorbent, its application fields have been widening. The absorption mechanism of HA is different for different materials, so the synthesis methods are required to be modified. However, the reports on the relationshiop between the absorption mechanism and prepartion technology are limited. In this review, the difference in the absorption mechanism for heavy metal ions and proteins is analyzed, and the relationship between the absorption mechanism and preparation technology is discussed. Moreover, the research tendency in this field is also pointed out.
