摘要：羥基磷灰石(hydroxyapatite，簡稱HA或HAP)是動物與人體骨骼的主要無機成分，具有良好的生物活性和生物相容性[1]，且HAP無毒、無致癌、無副作用，因此廣泛應(yīng)用于醫(yī)學(xué)。本文主要介紹羥基磷灰石的制備方法、表征、性能，以理論為基礎(chǔ)，結(jié)合實驗圖表與數(shù)據(jù)進行比較分析。采用共沉淀法,以Ca(NO3)2·4H2O、(NH4)2HPO4分別為鈣、磷源,用氨水調(diào)控溶液酸堿度合成了HA晶體，采用XRD、IR對所得HAP進行了表征，研究羥基磷灰石的吸附作用。 關(guān)鍵詞：羥基磷灰石；共沉淀法；吸附作用
Abstract：Hydroxyapatite is the main inorganic constituents of animal and human bones, with well bioactivity and biocompatibility, and HAP is non-toxic, non-carcinogenic and no side effects, it is widely used in medical. This paper describes the hydroxyapatite`s preparation methods, characterization and performance, theory based on experimental charts and data for comparative analysis. Coprecipitation, Ca (NO3)2• 4H2O﹑(NH4)2HPO4 were calcium, phosphorus source, the HA crystals synthesized with ammonia regulation of solution pH, income HAP were characterized by XRD、IR, research hydroxy apatite adsorption. Keywords：Hydroxyapatite；coprecipitation；adsorption |
