摘要 | In order to find a material which can be used for the recovery of Au(III), a chitosan derivative was synthesized by carboxymethylation and grafting sulfur groups onto cross-linked chitosan backbone. Adsorption studies were carried out at different pH values to optimize the pH condition. Batch method was conducted to study the effects of parameters such as reaction time, initial metal concentration and temperature on Au(III) sorption. The maximum adsorption affinity for Au(III) was found to be 8.32 mmol/g at pH 4.0, 25 degrees C. The results of kinetic study showed that the adsorption reaction followed the pseudo second order model. The derivative showed high adsorption ability and reusability toward Au(III). All results suggested that the chitosan derivative had potential to be utilized in the recovery of Au(III) from aqueous medium. (C) 2012 Elsevier B.V. All rights reserved. |
