Abstract
The removal of fluoride from drinking water is one of the most important environmental issues in the world. The problem of high fluoride in water sources in India and the rest of the developing world has exacerbated in the latest past due to increasing shortage of water. More people are being exposed to high water fluoride resulting in elevated levels of fluorosis in the societies. Fluoride (F) adsorption from solutions using Eleusine coracana seed powder from synthetic wastewater was studied on batch basis and results were tested with adsorption kinetic models to found the order of action. The equilibrium data was correlated to Temkin, Freundlich and Langmuir models and the maximum Freundlich adsorption capacity was found to be 4 mg/0.4 g.
