Quercetin and Gallic Acid containing Hydroxyapatites: Synthesis and Characterization

In the present study, hydroxyapatite (HAp) samples containing gallic acid or quercetin were synthesized using the wet chemical method. The synthesized samples were examined to ascertain the impact of gallic acid and quercetin incorporation on the structural and thermal characteristics of HAp. The samples were investigated using X-ray diffraction (XRD), Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), differential thermal analysis (DTA), scanning electron microscopy (SEM), and energy dispersive X-ray (EDX) spectroscopy. The XRD and FTIR results corroborate the formation of the HAp phase. It was observed that the addition of gallic acid and quercetin used in the synthesis had effects on the morphology, unit cell parameters, degree of crystallinity, and crystallite size. Additionally, the thermal analysis results indicate that gallic acid and quercetin exert a considerable influence on the thermal behavior of HAp.
