The shell of Pomacea sp has a potential application as raw material for the production of hydroxyapatite (HA). The preparation of HA was carried out at low temperature using a combination of ultrasound and microwave assisted radiation methods. In this experiment, hydroxyapatite was synthesized using citric acid as an organic modifier and Na2HPO4 as the source of PO 43-. The obtained products were analyzed by X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR), and Scanning Electron Microscope (SEM) to confirm the morphology and crystalline phase of HA. © 2014 Elsevier Ltd and Techna Group S.r.l.
