Description
Summary:Hydroxyapatite (HAp) is a mineral mainly composed of calcium and phosphorus that can be found in human bone and teeth. The environment is negatively impacted by large amounts of by-product waste from fishery factories. Hence, this study was conducted to extract biological natural HAp derived from waste black tilapia fish bones (BTFB) from a fishery industry. Fish bone could be a low-cost source of HAp with significant biomedical uses. The BTFB was calcined for 3 hours at 1000°C. Characterizations were done by using X-ray diffraction (XRD) for mineralogy, Scanning Electron Microscopy (SEM) for morphology and Fourier-transform infrared spectroscopy (FTIR) for the functional groups’ analysis. The extracted HAp was soaked in a simulated body fluid (SBF) solution for 7 days to evaluate biomineralization on the pellet surface. The XRD analysis confirmed the presence of derived HAp was compatible with standard HAp and the degree of crystallinity increases after calcination. The FTIR spectra confirmed that organic compounds were eliminated during the calcination process at 1000°C. After immersion in SBF solution, calcium phosphate crystal (CPC) nucleated on the pellet surface. Thus, these findings could be used as biomaterial in biomedical applications.
