    HaP/SBA-3 Nanostructured Composite to Remove Fluoride Effectively from Contaminated Water.
    (Univesidsad Tecnológica Nacional., 2021) Cussa , jorgelina; López, Claudia; Anunziata , Oscar Alfredo; Anunziata , Oscar Alfredo; López, Claudia
    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. Keywords: F- retention; Contaminated water; HaP/SBA-3; Nanocomposites

    HaP/LP-SBA15 Nanocomposite for efficient removal of fluoride from contaminated water.
    (Univesidsad Tecnológica Nacional., 2020) López, Claudia; Cussa, jorgelina; Anunziata , Oscar Alfredo; Anunziata , Oscar Alfredo; Cussa, jorgelina
    Hydroxyapatite (HaP) composites and highly ordered large pore mesoporous silica, such as LP-SBA 15 (Large Pore-SBA-15), were developed, characterized by XRD, BET, FTIR, and HRTEM, applied to fluoride removal from contaminated water. The proposed procedure to prepare HaP/LP-SBA-15 was successful, which acts as supports to anchor the HaP crystals, in nanometer-scale (<12 nm), with higher fluoride retention from contaminated water. The free OH- groups of HaP nanocrystals, inside the host, permitted fluoride retention with high capacity. The fluoride holding activity was over 3 orders of magnitude higher than pure HaP.

    Efficient retention of fluorides using SBA-3mesoporous Material.
    (Univesidsad Tecnológica Nacional, 2022) Cussa, Jorgelina; López , Claudia; Anunziata, Oscar Alfredo; Anunziata, Oscar Alfredo
    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 was successful, which acts as supports to anchor the HaP crystals, in nanometer-scale (<2 nm), 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.
