<P>PROBLEM TO BE SOLVED: To provide a noble metal absorbent capable of selectively adsorbing a noble metal at low material cost and a low cost for production process, and to provide a method for adsorbing selectively adsorbing only the noble metals such as gold and platinum using the noble metal adsorbent. <P>SOLUTION: The noble metals are collected by adsorbing the noble metals from a solution in which the noble metals are dissolved by using the particulate noble metal absorbent formed by introducing a graft chain in which a monomer containing a dialkylaminoalkyl (meth)acrylate on a particulate base is polymerized. <P>COPYRIGHT: (C)2013,JPO&INPIT |
