Abstract
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.
