摘　　要：羟基磷灰石具有良好的吸附性能和生物相容性,在水体污染治理中,羟基磷灰石是一种理想的环境友好型吸附剂。羟基磷灰石能够通过络合反应、溶解—沉淀作用以及离子交换反应对水体中的重金属、氮磷、有机物等污染物进行去除,在一定条件下,可以大幅降低污染物在水体中的含量,达到水体污染治理的目的。总结了羟基磷灰石不同的制备方法,介绍了羟基磷灰石吸附处理的机理和羟基磷灰石作为吸附剂在水体污染治理中的应用。Hydroxyapatite has good adsorption properties and biocompatibility,which makes it an ideal environment-friendly adsorbent in water pollution treatment.Hydroxyapatite can remove heavy metals,nitrogen and phosphorus,organic matter and other pollutants from water bodies through complexation reaction,dissolution-precipitation and ion exchange reaction,and under certain conditions,it can significantly reduce the content of pollutants in water bodies and achieve the purpose of water pollution treatment.This paper summarizes different preparation methods of hydroxyapatite,focusing on the mechanism of adsorption treatment of hydroxyapatite and the application of hydroxyapatite as an adsorbent in water pollution treatment.
