Fluoride is often called a two-edged sword. In the human system, this fluoride has a dual personality, a destructive effect (>1.5 ppm – dental and skeletal fluorosis), and a beneficial effect (up to1.0 ppm – caries prevention and health promotion). World Health Organization recommends that the fluoride content in drinking water should be in the range of 1.0–1.5 ppm. Fluoride concentrations beyond the standards cause dental and skeletal fluorosis. Among various methods used for defluoridation of water, adsorption method is relatively simple, economical, and appropriate for drinking water treatment, especially for small communities. In this review, a list of various adsorbents and their adsorption capacities for fluoride are overviewed with various affecting parameters. |
