Fluorine is the 13th most abundant and lightest member of the halogens. It is highly electronegative, and reactive of all the elements that is why it is not found as elemental fluorine. Double-edged sword is the name given to fluorine because inadequate intake causes dental caries while as excess causes fluorosis. Fluorosis is condition that cannot be reverted back, the only solution is the prevention and that is done by defluoridation. Defluoridation methods are broadly divided into coprecipitation, adsorption ion exchange, contact precipitation, electro-coagulation and membrane process. Activated Aluminum is found efficacious for defluoridation processes by domestic methods. This paper is a review on defluoridation studies of conventional materials by using methodologies such as ion exchange, precipitation and adsorption
Keywords: Fluoride, Defluoridation, Activated Alumina; Domestic Defluoridation.
