摘要

Proteins exhibit specific interactions with various metal ions,which play important roles in a living cell.Here,we found that various proteins selectively adsorbed precious metal ions at a wide range of pH values.Studies on protein sequences and on synthesized peptides revealed that a histidine-containing sequence had specific interactions with precious metal ions (Au3+ and Pd2+).We then investigated a few types of protein-rich biomass as adsorbents for precious metal ions.In the presence of various transition metal ions,Au3+ and Pd2+ were also selectively adsorbed onto the biomass tested.The bound precious metal ions were recovered by aqua regia after charring the metal-bound biomass.Finally,we demonstrated the successful recovery of Au3+ and Pd2+ from a metal refining solution and a metal plating waste using the biomass.We propose an environmentally friendly recycling system for precious metal ions using protein-rich biomass.
