Research Abstract

We prepared peptide-grafted silica particles as a new column packing material in order to collect noble metal ions from their dilute aqueous solution. We have carried out Au ion recovery experiments by using columns packed with peptide-grafted silica particles, which have various graft density of the peptide chains. It was revealed that the surface density of the peptide chains was an important parameter to decide the adsorption amount and the desorption amount of Au ions.
