| Outline of Final Research Achievements |
Peptides were immobilized on the surface of the silica particles for column packing material, and the peptide-modified particles were used as metal ions scavenger. The peptide used in this study were polylysine and polyglutamic acid, which have ionic side chain groups. Adsorption experiments of noble metal ions with the peptide-modified silica particles revealed that the particles showed high adsorption selectivity for gold ion. Therefore, the column filled with the peptide-modified silica particles may perform gold ion selectivity from a mixed ions solution. We also estimated desorption from the particles after the metal ion capturing, and the desorption efficiency was clarified to be practical enough.
