Opis

This book discusses the problems and feasible remediation of fluoride contamination in groundwater. The book investigates applications of various carbons derived from bio-mass and bio-polymers. It also inquires into surface modified carbons that use inorganic ions to help remove excess fluoride ions in drinking water and wastewater effluents. The compliance of kinetic and isotherm models with fluoride sorption is covered, and the suggested mechanisms of defluoridation by surface modified carbon materials is described.
