Characterization of Cr(VI) Removal from Aqueous Solutions by Natural Hydroxyapatite from Bone Ash and Determination of Optimum Conditions


The aim of this paper is eliminating Cr(VI) by natural HAP. HAP is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like Cr(VI). Some experiments in different pH are performed (pH = 2, 3, 7). Maximum adsorption was appeared at pH = 2, dosage = 0.3 gr, C0 = 10 mg/l. Cr(VI) removal depends on pH value and initial amount of Cr(VI) result of experiments were analyzed by Longmuir and Freundrich and kinetic model.
