Abstract
Highly ordered pore mesoporous silica composites, like SBA-3 and
hydroxyapatite (HaP) nanocrystals, characterized by X-ray diffraction
(XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron
Microscopy (SEM), Transmission Electron Microscopy (TEM) and textural
properties, were successfully applied to remove fluoride from contaminated
water. The proposed procedure to prepare HaP/SBA-3 wassuccessful, which
acts as supports to anchor the HaP crystals, in nanometer-scale (<2nm), with
higher fluoride retention from contaminated water. The free OH- groups of
HaP nanocrystals, within the host, facilitated the high-performance fluoride
trapping. The fluoride retention activity was much higher than that of pure
HaP and the composites HaP/SBA-15 and HaP/MCM-41.
