Abstract
This work studies the cationic surfactant effects (CTAB) on the morphology and particle size of the hydroxyapatite (HAp), using the microwave method keeping the pH, time and temperature constant. The obtained products were characterized using transmission electron microscopy, X-ray diffraction, FT-IR and EDS spectroscopy. TEM results showed that surfactant had great impact on size of hydroxyapatite. The smallest nanorods structures with mean size of 43.17 nm in diameter and 136.52 nm in length were obtained by using 0.45w% [in proportion of Ca and P precursors] of surfactant. XRD analysis confirmed the presence of hexagonal hydroxyapatite and showed the crystallite size dimensions by Rietveld analysis. FT-IR technique corroborated the HAp presence by characteristic vibrational modes and EDS spectroscopy displayed the Ca/P ratio in all the samples. This work could be taken into account as a base for composite biomaterials development for gas sensing and biomaterial applications.
