Comparison of raw materials and preparation methods for seashell hydroxyapatite
摘要
Abstract
In the present study,we used CaO and calcined oyster,clam,scallop,and snail shells as raw materials to synthesize nanohydroxyapatite(HA)using the reverse-phase microemulsion method and polyethylene glycol(PEG)-assisted microwave heating and compared the physicochemical characteristics and morphological parameters of HA.Fourier transform infrared spectroscopy and X-ray powder diffraction were used to characterize the product,scanning electron microscopy was employed to observe the surface morphology,and a Zeta potential analyzer was utilized for potential determination.The results showed that HA fabricated using the reverse-phase microemulsion method had a particle size between(104.10±1.95)and(207.90±3.75)nm and a sphere-like morphology;however,HA prepared using the PEG-assisted microwave method presented a smaller particle size that varied from(61.17±3.11)to(182.70±1.05)nm and tended to have an oval-like and rod-like shape,while showing better stability and hydrophilicity.In addition,compared with chemically synthesized HA,HA derived from seashells had a better nanostructure,and HA derived from snail shells outperformed others in terms of particle size,stability,and wet-tability.Furthermore,the Ca/P ratio of snail-shell HA was closer to that of the natural bone.Therefore,snail shells can be used as the main raw material for synthesizing HA using the PEG-assisted microwave method.关键词
