Abstract The present study reveals one-step, rapid and cost-effective preparation of nanohydroxyapatite (nHAp) from fish bones and mussel shells via microwave-assisted method. Fish bones and mussel shells facilitate the calcium (Ca) that reacts with ethylenediaminetetraacetic acid (EDTA) to form Ca-EDTA. Microwave irradiation of Ca-EDTA and disodium hydrogen phosphate (Na2HPO4) mixture at 750 W for 10 min resulted in HAp or Ca10(PO4)6(OH)2. Samples were analyzed using diffraction, spectroscopic, microscopic and thermal techniques. High quality and thermally stable nanocrystals were present in fish bones and mussel shells HAp samples, with average particle size of 265 nm and 108 nm respectively.

微波辅助从鱼骨和贻贝壳中一步合成纳米羟基磷灰石

摘要 本研究揭示了通过微波辅助方法从鱼骨和贻贝壳中一步、快速且经济地制备纳米羟基磷灰石 (nHAp)。鱼骨和贻贝壳促进钙 (Ca) 与乙二胺四乙酸 (EDTA) 反应形成 Ca-EDTA。Ca-EDTA 和磷酸氢二钠 (Na2HPO4) 混合物在 750 W 下微波照射 10 分钟，产生 HAp 或 Ca10(PO4)6(OH)2。使用衍射、光谱、显微和热技术分析样品。鱼骨和贻贝壳 HAp 样品中存在高质量和热稳定的纳米晶体，平均粒径分别为 265 nm 和 108 nm。
