羟基磷灰石复合吸附剂对去除水体中阴离子的研究进展
|
摘要
羟基磷灰石(HAP)作为一种良好的吸附材料,在环境领域有着广泛的应用。但未经处理的HAP吸附容量较小,易团聚,严重制约其应用。因此,本文从制备技术、吸附机理方面综述了近几年来HAP复合材料作为阴离子处理吸附剂的研究进展,并对其在此领域未来的研究方向进行展望。
Hydroxyapatite(HAP)is a material with excellent adsorption properties, which is widely used in environmental field. However, the disadvantages of low adsorption capacity and easily aggregation for the untreated HAP restrict its application. The research progress of hydroxyapatite composite materials in the treatment of anion wastewater waste water is reviewed. Preparation methods are discussed and adsorption mechanism is introduced. In the end, the future research directions of HAP in the removal of anions is suggested.
