Abstract

Hydroxyapatite (HAP) is an effective adsorbent for removing heavy metal ions. In this study, HAP was prepared by sol-gel method and used for removing Cu2+ from aqueous solution. Initial concentration of Cu2+ in the aqueous solution was evaluated as an important parameter determining uptake. The removal efficiency and the adsorption capacity of HAP for Cu2+ were investigated. EDS analysis indicated the presence of Cu2+ on the HAP surface.
