Abstract

Abstract: The nano‐structured hydroxyapatite was prepared from pig bone materials by mineralization. The obtained nano‐structured bone was much better compared to the bone without nanostructure for removing Pb 2+ . The process was investigated under different conditions including contact time, initial Pb 2+ concentration, and pH. The pseudo‐second‐order kinetic model and Langmuir isotherm model were suitable for describing adsorption process. Moreover, the maximum adsorption capacities of nano‐structured bone and bone without nanostructure were 312.5 and 96.1 mg/g, respectively. Overall, the advantages of excellent adsorption capacity and simple mineralization together with low cost make nano‐structured bone an attractive material for removal of Pb 2+ from aqueous solution.
