摘要: Abstract The adsorption of fluoride from water on bone char (BC) was investigated in this work, and the capacity BC compared to that hydroxyapatite (HAP). HAP drastically increased while decreasing pH 7.0 5.0. Furthermore, due its content not considerably affected by presence anions Cl − , HCO 3 CO 2− SO 4 NO 2 . mechanism attributed electrostatic interactions between surface charge ions solution.
