Beschreibung
Zusammenfassung:	Provided are a noble metal adsorbent, a method for recovering a noble metal, and a method for regenerating a noble metal adsorbent that can easily recover noble metal while high adsorption performance for noble metals is achieved. The noble metal adsorbent according to the present invention includes a metal sulfide. The metal sulfide is constituted of, for example, molybdenum disulfide particles. The method for recovering a noble metal according to the present invention includes adsorbing a noble metal onto the noble metal adsorbent, and thereafter heating and volatilizing the noble metal adsorbent in the presence of oxygen to recover the noble metal.
