Abstract- Urbanization and industrialization cause various changes in the environment and the resulting chemical and organic matter causes various harms to living things in this world and this harm also affects future generations. Fluoride, one of the wastes from the fertilizer industry and some manufacturing plants, mixes with water and causes various anatomical and various harms when it is ingested by organisms. Its concentration can be reduced more easily by the absorption method than by various methods to remove fluoride from water, this is called defluoridation. Fluoride, which has an opposite charge property, can be easily removed by a positively charged material. Part of this can be removed by absorption with an aqueous solution made from the cover of tamarind fruit.
