摘要：
Hydroxyapatite nanostructures were synthesized by microwave irradiation from egg shells. This nanoadsorbent was used for effective removal of lead ions from water and wastewater samples. The effects of experimental conditions such as pH, temperature, contact time, dose of adsorbent and initial concentration of lead ions on removal were investigated. Langmuir and Freundlich isotherms were studied, and the results indicated that the adsorption mechanism was based on Langmuir isotherm. The synthesized nanoadsorbent shows high adsorption capacities for removal of lead ion from water samples.
