Özet

Recently, several organic and inorganic adsorbents are used for the separation and purification processes of metal ions and removal of radionuclides from radioactive and industrial wastes. In this study, calcium hydroxyapatite was prepared by phosphogypsum waste and its adsorption behavior towards lead-210 was evaluated. Results showed that the adsorption percentage of hydroxyapatite was found to be 95% on the optimum conditions. Additionally, the adsorption kinetic data were analyzed using pseudo-first order and pseudo-second order kinetic models. The results indicated that hydroxyapatite is an efficient adsorbent for the removal of lead-210 from aqueous media with good performance.
