Lanthanum-doped silica xerogels for the removal of fluorides from waters.
M. Hernández-Campos,A.M.S. Polo,Manuel Sánchez-Polo,José Rivera-Utrilla,M.S. Berber-Mendoza,G. Andrade-Espinosa,María Victoria López-Ramón +6 more
TL;DR: Chemical characterization of materials confirmed that fluoride removal from waters is due to the precipitation of LaF3 on the surface of La-doped xerogels, and analysis of the influence of solution pH revealed that the adsorption capacity of all xerOGels was highest at a solution pH of 7.7.
