Abstract: Based on the rice husk biochar(BC), a creative hydroxyapatite(HA)-biochar composite (HAC) was fabricated in this study. SEM coupled with EDS, BET and XRD were employed to analyze the surface features and pore structures of BC, BC+HA (the mixture of BC and HA) and HAC. The effects of solution initial pH and the contact time between sorbents and Cd were also investigated. The results revealed that, on the surface of HAC, HA was well loaded. Though initial pH and contact time would significantly influence the adsorbing effects of Cd by all three sorbents, HAC showed a high efficient and capacity to adsorb Cd (II) in the aqueous solutions than simple biochar, and a low cost than adding nano-HA.
