摘要：Sodium calcium borate glass derived hydroxyapatite (G-HAP) scaffolds were prepared by dipping with polymer foam. The effects of glasses and ethyl-cellulose (EC) content on the porosity and compressive strength of the scaffolds were studied. The effects of different initial pH value and ions concentration on adsorption performance of copper ions in aqueous solutions were also investigated. The results showed that G-HAP scaffolds could immobilize copper ions in solution effectively. The mechanism of G-HAP scaffolds in immobilizing Cu2+ ions from aqueous solutions was investigated by the X-ray diffraction, Infrared Spectra and Scanning electron microscopy-Energy Dispersive Spectrometer.
