We propose to employ metal organic frameworks as novel and effective adsorbents for the removal of fluoride based compounds from water. It is hypothesized that these fluoride based compounds can be removed from water via size exclusion, and selective adsorption on the surface of the proposed metal organic frameworks. This research has the potential to be quite significant from both a scientific and a technological perspective. The proposed research aims to have a fundamental understanding on transport and adsorption mechanisms of different fluoride based compounds present in untreated water through metal organic frameworks. When successful, the proposed research will result in the development of an innovative separation system capable to effectively separate undesirable chemicals from water, and potentially in a viable approach to reduce the costs associated to water treatment.
