| Popis: | In the present study, phosphogypsum waste (PG) was utilized to synthesize fluorapatite (FAP) via a simple precipitation method. The FAP was prepared using a novel mixing technique with anhydrite obtained from PG and phosphoric acid solution in the presence of pure fluoride ammonium in a Teflon reactor. The characteristics of the prepared FAP were investigated with various methods including Scanning Electron Microscopy (SEM) coupled with Energy-Dispersive Spectroscopy (EDS), X-Ray Diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FTIR). The FAP derived from PG exhibited a hexagonal structure with a particle size ranging from 1.5 to 9 μm along with a high purity. FAP also showed an excellent Ca/P ratio equals to 1.67. These results proved that the FAP was successfully synthesized from phosphogypsum waste. |
