摘要：A new adsorbent has been developed by microwave-induced carbonization with persimmon tannin, and its adsorption behaviors and mechanism towards Au(III) were studied in hydrochloric acid medium. The adsorption of Au(III) was found to be dependent on acidity, temperature, reaction time. The maximum adsorption capacity was above 700 mg g-1. The selective recovery of Au(III) by adsorption-elution experiment was tested to be effective, and the loaded metals can be easily desorbed by acidic thiourea. Characterized by FTIR and SEM, the adsorption mechanisms of Au(III) was proposed to be redox-reduction.
