Preparation of Hydroxyapatite from Dromedary Bone by Heat Treatment

The objective of this work is the preparation of hydroxyapatite by femur dromedary bone heat treatment. The treatment was carried out at temperatures up to 1000 degrees C, and the powders obtained were characterized by Fourier Transform Infrared Spectroscopy, X-ray diffraction, X-ray fluorescence spectrometry, and laser granulometry. The results show that the extracted powder corresponds to a hydroxyapatite whose crystallinity increases with the increase of the calcination temperature. The removal of the organic matter from 600 degrees C leads to a white powder of nanoporous structure. The chemical analysis of the calcined powder shows the presence of the major calcium and phosphorus elements with atomic ratio Ca/P=1.62. The powder also contains ions' trace such as sodium, magnesium strontium, and zinc. The dromedary bone can be considered as a new source of hydroxyapatite whose applications can be extended from biomedical to environmental remediation.
