摘要
通过煅烧和化学提取从绿贻贝壳和牛骨中回收钙和磷酸盐是富碳酸盐磷灰石生物医学材料应用的可行前体。由于富含碳酸盐的磷灰石生物陶瓷具有高骨传导性,目前正在对其用于合成骨移植进行深入研究。本研究采用煅烧和在氯化镁和 H2SO4 中进行化学溶解的粉末加工方法,分别回收贻贝壳中的钙和牛骨中的磷酸盐,得到可用于微波辐照合成的晶体形成溶液原料。傅立叶变换红外光谱和 X 射线衍射图验证了合成粉末的结晶度和相鉴定。因此,傅立叶变换红外光谱中出现了碳酸盐-磷酸钙复合物中的 CO3、PO43- 和 OH-条带。根据 XRD Rietveld 方法,合成的粉末产品中含有刷石、碳化羟基磷灰石(CHA)、方解石和石膏。可回收的 CHA 结晶大小为 40 纳米。本研究表明,微波辐照合成 CHA 粉末与从蚌壳和牛骨中提取的钙和磷酸盐有可能产生大量用于生物陶瓷的 CHA,并有助于设计制备生物医学应用中 CHA 粉末前体的粉末加工步骤。
Microwave-assisted hydrothermal synthesis of carbonated apatite with calcium and phosphate resources derived from green mussel shell and bovine bone wastes
Resources recovery of calcium and phosphates from respective green mussel shells and bovine bones by calcination and chemically extracting are viable precursors for carbonate-rich apatite biomedical material applications. Because of their high osteoconductivity, carbonate-rich apatite bioceramics are being studied intensively for synthetic bone transplants. In the study, powder processing routes of calcination and following chemical dissolution in MgCl2 and H2SO4 were each for recovering calcium of mussel shells and phosphate of bovine bones yielding a crystal-forming solution feedstock for use in microwave-irradiated synthesis. FTIR spectra and XRD patterns validated the crystallinity and phase identification for as-synthesized powders. As a result, the presence of CO3, PO43-, and OH- bands in carbonate-calcium phosphate complexes were present in FTIR spectra. According to the XRD Rietveld method, the as-synthesized powder product contained brushite, carbonated hydroxyapatite (CHA), calcite, and gypsum. The recoverable CHA crystallites' size was 40 nm. This present study demonstrated that microwave irradiation synthesis of CHA powder with calcium and phosphates derived from mussel shells and bovine bones is the potential to yield a large amount of CHA for bioceramics and would aid in the design of a powder processing step for preparing the CHA powder precursor in biomedical applications.
