Removal of Fluoride from Water by using Natural Adsorbent

Abstract

Abstract: Access to safe drinking water is not only the elementary need of human being but also honored as an mortal right .For overall development of the country , as acceptable nutrition, education, gender equivalency, and particularly the eradication of poverty in developing countries are required , along with that furnishing safe drinkable water is equally important . Fluoride one of the water quality parameters of concern, with redundant( beyond1.5 mg/ l, World Health Organization( WHO) guideline value of what contaminates groundwater coffers in numerous corridors of the world, and renders it not drinkable for mortal consumption, due to affiliated adverse health goods thus, knowledge of its junking, using the stylish fashion with optimum effectiveness demanded . Taking the inflexibility of the problem into consideration, the present paper aims to give a retrospective approach to the use of effective low- cost adsorbents for the junking of fluoride from water . The defluoridation capacity of certain low- cost natural adsorbents like Groundnut shell powder and Soya chunk powder were added in the list and discussed. The effect of pH, adsorbent dose, initial concentration , and contact time also delved . It's set up that the junking of Fluoride ions at optimum parameters like pH, adsorbent dose ,initial concentration and contact time is at 7, 2gm, 5mg/ l, and 100 minutes respectively for groundnut shell powder and 6, 2gm, 5mg/ l, and 100 minutes respectively for Soya chunk powder. For all optimum parameters, the maximum reduction in Fluoride ions observed in the range of 55 to 65% for groundnut shell powder whereas for soya chunk powder it's 40 to 50%
