Hydroxyapatite forming method, hydroxyapatite and application of hydroxyapatite
The invention discloses a forming method of spherical hydroxyapatite, hydroxyapatite and application of the hydroxyapatite. The forming method specifically comprises the following steps: uniformly stirring and mixing a calcium chloride aqueous solution and an ammonium dihydrogen phosphate aqueous solution, filtering to obtain a hydroxyapatite precipitate, and directly dispersing the hydroxyapatiteprecipitate into deionized water without washing to obtain a turbid liquid; and mixing the hydroxyapatite turbid liquid and an alginate aqueous solution to form slurry, then adding the slurry into ametal salt solution in a dropwise manner, solidifying the hydroxyapatite into gel balls, and drying and roasting to obtain the spherical hydroxyapatite. The preparation method is simple in process, and the prepared spherical hydroxyapatite is high in sphericity degree and strength and has wide application prospects in the fields of catalysis, adsorption separation and bioengineering.
本发明公开了一种球形羟基磷灰石的成型方法及羟基磷灰石和应用，具体为先将氯化钙水溶液和磷酸二氢铵水溶液搅拌混合均匀，过滤后得到羟基磷灰石沉淀物，不经洗涤直接分散到去离子水中得到悬浊液；将羟基磷灰石悬浊液和海藻酸盐水溶液混合成浆液，然后把该浆液滴入到金属盐的溶液中，羟基磷灰石凝固成凝胶球，经干燥焙烧后得到球形羟基磷灰石。该制备方法工艺简单，制备到的球形羟基磷灰石球形度高，强度大，在催化、吸附分离和生物工程领域具有广阔的应用前景。
