摘要
采用微乳液法与水热合成法相结合的合成手段,探索新的羟基磷灰石纳米材料合成方法,通过改变实验参数,制备出不同形貌的纳米羟基磷灰石,并考察其表面形貌对重金属离子(Pb2+)吸附性能的影响。
Hydroxyapatite has excellent surface properties and ion exchange adsorption properties because of its particular crystal chemistry characteristics.It has become a new environmentally functional mineral material.In this paper,microemulsion and hydrothermal method were combined for the synthesis of hydroxyapatite nanomaterals.Spherical and rod-shaped hydroxyapatite nanomaterials were prepared by changing the reaction parameters,and their surface adsorption performance by Pb2＋ ions was also studied.The results of the research could provide a new direction in the treatment of heavy metal ions in wastewater.
