Fluorosis is a public health problem in many parts of the world. The major source of fluoride intake is drinking water. Fluoride contamination in drinking water due to natural and anthropogenic activities has been recognized as one of the major problems worldwide imposing a serious threat to human health. Excess fluorides can cause skeletal and dental fluorosis. There are many ways for fluoride removal viz Electrocoagulation, Ion exchange, adsorption etc. But among them adsorption is very popular, because of its simplicity and a lot of adsorbents available. Adsorption process has been explored widely and offers satisfactory results. The permissible limit of fluoride concentration in drinking water is 1.5mg/L according to WHO guidelines. As cost is an important consideration in most developing countries, efforts have been made to explore the possibility of using various low cost adsorbents that are abundant, readily available and are derived from agro waste materials like Ashoka (Polyalthia) leaves, Orange peels and Bael leaves (Aegle marmelos) leaves. There are using Aluminium impregnated agro wastes charcoal for fluoride remediation. These adsorbents efficiency of eliminating fluoride is studied with different parameters such as pH, agitation time, adsorbent dose, temperature and initial fluoride concentration. Moreover, desorption of fluoride from impregnated Bael leaves and orange peels gives 96% fluoride leaching at pH 5.5. Impregnated Ashoka leaves gives 92% fluoride removal at pH 5.5 but it takes a large agitation time and adsorbent dose with respect to Bael leaf or Orange peel. Reference [1] V. Tomar, D.
