Study on Synthesis of Carbonated Hydroxyapatite under Different Conditions and Its Adsorption Property
摘要
Abstract
Using ions coprecipitation method, four kinds of carbonated hydroxyapatites ( CHA ) were synthesized by changing addition way and order of CO2-3 . The phase composition, chemical composition, micromorphology of obtained CHA were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, Scanning electron microscope, respectively. The results showed that four kinds of samples were carbonated hydroxyapatite partially substituted (including Type-A and Type-B ) by CO2-3~. The substitution amount, which reflects the degree of lattice distortion and has some influence on adsorption performance as a result, was sample 2 > sample 1 > sample 3 > sample 4 from large to small order. In order to compare the adsorbability of four samples, the experiments on adsorption of Cu2+ in an aqueous solution were done and the results showed that the removal rate of Cu2+ of four samples are far above that of standard HA, with sample 2 leading the way and reaching 99. 42% .关键词
