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 resea...
