Carboxylate-modified apatite adsorbents for detection of Zn(II) ions

Abstract

A B S T R A C TThe presence of heavy metals in the environment is a major issue for ecosystems and human health. Among possible remediation strategies, this study was devoted to the preparation of hybrid materials based on hydroxyapatite in order to obtain an improved Zn immobilization property. In particular, we have developed carboxylate-hydroxyapatite nanocomposites, which associate a good affinity towards Zn(II) species compared to the pure hydroxyapatite. Results of Zn sorption have been discussed in this study and compared to Pb(II).
