Abstract

Heavy metals REMOVAL by adsorption processes as general mechanisms to reduce the damage caused by heavy metals is considered. Due to a variety of reactive surface area on hydroxyapatite and cationic and anionic exchange capability, it was a matter of considerable ability is to absorb and remove heavy metals. In this study, the ability to remove heavy metal ions Pb2+and Ni2+ and placed in the structure of apatite by the method of acid-base from aqueous solution analysis. Order of elements in solution was considered so that the atomic ratio of Ca/P, Pb/P and Ni/P is equal to 1.67. Then both acid-base reacted to form APATITE STRUCTURE were carried out. The precipitate obtained by the techniques of XRD, FT-IR, and TEM were reviewed and evaluated. The results showed that apatite deposition method is able to eliminate lead and nickel ions from solution are almost complete. REMOVAL mechanism of lead and nickel ions can be formed into sedimentary APATITE STRUCTURE or form calcium ions hydroxyapatite and adsorption of nickel and lead in calcium hydroxyapatite and cation exchange considered.
