摘要：

Hydroxyapatite (HAp) nanorods are synthesized from phosphogypsum waste (PG) and potassium dihydrogen phosphate (KH2PO4) under hydrothermal conditions. The influence of several synthesis parameters such as temperature (100-200 degrees C), synthesis time (1-15 h), and solution pH (5-11) on product structure and purity is addressed by X-ray diffraction and Fourier Transformed-Infrared Spectroscopy. Phase-pure HAp nanorods with diameter and length of 18 and 63 nm, respectively, are obtained after 10 h at 200 degrees C and pH similar to 11. The influence of Brij-93 surfactant on the morphology of prepared HAp is investigated by transmission and scanning electron microscopy. The aspect ratio and the mean size of HAp crystals increase to 1013 and 205 x 20 nm, respectively, with increasing the concentration of Brij-93 surfactant to 0.01 mol. Hence, the PG recycling could be accomplished using an easy synthesis route with relatively cheap reactants for the production of nanocrytalline HAp.
