description | PROBLEM TO BE SOLVED: To provide a noble metal adsorbent and a recovery method of a noble metal, which can separate and recover a specific kind of a noble metal from other noble metals and base metals.SOLUTION: The noble metal adsorbent is prepared by chemically modifying algae, residues thereof, or strong acid-treated substances thereof with a functional group containing a nitrogen atom and/or a sulfur atom. The functional group includes, for example, dithiooxamide or a polyethyleneimine. The noble metal adsorbent has an application to adsorption of platinum or palladium. A noble metal dissolved in a solution is made to be adsorbed by a noble metal adsorbent described in claim 1, 2 or 3 to thereby recover the noble metal. |
