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 was successful, 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.
