Today, one of the most important issues all is supply drinking and utility water, which basic need for human beings, to be healthy reliable, economical. Some substances in natural water sources pose a danger living creatures when they exceed certain concentrations. Fluoride, can commonly found as result or industrial effects, poses various risks not only its deficiency, but also excess. Therefo...

This research is focused on the search of a biomass for the sequestration of fluoride from drinking water. Defluoridation of water was studied by batch experiments in biosorption process. The biomass was found to reduce fluoride to permissible limit 1.5 mg/L as prescribed by WHO. The efficiency of the sorption process was investigated under different experimental parameters such as pH 7, standi...
