【摘要】：室温离子液体作为溶剂,以离子热合成法合成了羟基磷灰石超细粉体。当改变不同的离子液体作为溶剂时,可以相应调整羟基磷灰石的形貌。对羟基磷灰石分别采用X-射线粉末衍射(XRD),扫描电子显微镜(SEM),傅立叶变换红外光谱仪(FTIR)等进行表征。实验结果表明:所得到的羟基磷灰石为部分CO32-取代的羟基磷灰石,在选用EmimBF4为溶剂时所合成样品颗粒的尺寸、形貌更加规则、均一。与水作为溶剂相比,以离子液体BmimBr作为溶剂所合成的羟基磷灰石材料对有机染料碱性品红的饱和吸附量为43.78 mg·g-1,具有较好的吸附性能。
[Abstract]:Hydroxyapatite ultrafine powder was synthesized by ion-thermal synthesis with room temperature ionic liquid as solvent. The morphology of hydroxyapatite can be adjusted when different ionic liquids are used as solvents. Hydroxyapatite was characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The experimental results show that the hydroxyapatite obtained is partially CO32- substituted hydroxyapatite. The size, morphology and uniformity of the synthesized particles are more regular and uniform when EmimBF4 is used as solvent. Compared with water as solvent, the saturated adsorption capacity of hydroxyapatite prepared with ionic liquid BmimBr as solvent was 43.78 mg / g ~ (-1) for organic dye basic fuchsin.
