      At a solution pH value below 6, the surface of AA has a positive charge and thus possesses an excellent capacity for fluoride adsorption (Ghorai and Pant 2004, López Valdivieso et al. 2006). At the neutral pH range, the affinity of the surface for fluoride is much lower, limiting the practical applications of AA (Hiemstra and Van Riemsdijk 2000).
