Removal of Fluoride by Biochar Prepared from Natural Waste (COCOS NUCIFERA)

Abstract

Abstract: Water is life since it supports the existence of all biota. The provision of clean water has indirectly become essential to how well people live nowadays. Water, one of the most abundant and necessary elements in nature, is at risk of being highly polluted due to a variety of factors, despite the fact that it is an important component of the flora and fauna and makes up roughly 75% of the earth's crust. Ground water is frequently contaminated with fluoride. Fluorosis is brought on by the overabundance of fluoride in drinking water. The World Health Organization (WHO) guidelines state that 1.5 mg/l of fluoride is the maximum amount that should be present in drinking water. Investigated were the adsorption processes used to remove fluoride ions from ground water. The goal of this research is to create an environmentally friendly, cost-effective adsorbent for removing fluoride from ground water that can be used in rural areas of many developing nations. Fluoride elimination uses biochar made from natural waste (Cocos Nucifera). The effects of many parameters on adsorption tests, such as adsorbent dose (0.5–2 gm), starting fluoride concentration, have been revealed through batch experiments (10-50ppm). Fluoride elimination was observed using the UV Spectrophotometer.The adsorbent(coconut fiber) showed the maximum defluoridation capacity of 80%.The adsorbent(coconut shell) showed the maximum defluoridation capacity of 90%.
