Kinetics of fluoride removal from drinking water by ion exchange method

Abstract

High concentrations of fluoride occurring naturally in ground or drinking water cause the bone disease fluorosis among local populations. Therefore, lowering of fluoride to a certain concentration in drinking water is required. One of the various methods applied for this purpose is ion exchange method. In this study, a strong basic ion exchange resin, Purolite-250, having the chemical form R-N(CH3)(2)C2H4Cl, was used for removing fluoride ions.
