Abstract:
A precious-metal adsorbent is chemically modified by a functional group including an N atom and/or an S atom, and is formed from one of an alga, a residue of the alga, a substance obtained by treating the alga with a strong acid, and a substance obtained by treating the residue of the alga with a strong acid.
