Adsorption Study of Carbonate Hydroxylapatite for Hexavalent Chromium Ion from Aqueous Solution at Different Carbon Content

Article Preview

Abstract:

The adsorption of Cr6+ from aqueous solution by carbonate hydroxylapatite (CHAP) with different carbon content synthesized by precipitation. The CHAP was characterized and analyzed by TEM、FTIR and XRD. And adsorption was effected by the pH value、CHAP usage、adsorption time and other factors. The results show that under certain conditons, adsorption capacity enhanced with the carbon content increasing.
