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.pdfeninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/F-retentionWaterHap/LP-SBA-15Nanocompositesinfo:eu-repo/semantics/articleLópez, Claudia; Cussa, Jorgelina; Anunziata, Oscar Alfredo.https://creativecommons.org/licenses/by-nc-nd/4.0/
