Fluoride is one of the common contaminants present in groundwater and in waterbodies in general. It can create serious health hazards if ingested more (>1.5 mg/L). Scientists understands that removing fluoride from ground water is a difficult task. Several techniques like coagulation, membrane filtration, etc. are available for treatment but because of the high processing costs, such technologies are not always suitable for developing countries. As a result, environmentally friendly and low-cost technology like adsorption is one such method that can be successfully employed for fluoride removal. Fluoride was removed using a variety of low-cost adsorbents such as tamarind seed, tamarind gel, and duck weed etc. by defluoridation using adsorption and can be considered as one of the efficient and practical technique.
