<P>PROBLEM TO BE SOLVED: To provide a noble metal selective collection agent and a method of selectively collecting noble metal from noble metal-containing liquid, which allow separation, precipitation and collection of noble metals from noble metal-containing liquid with high selectivity. <P>SOLUTION: The noble metal selective collection agent includes a cationic polymer compound as an active ingredient. The method of selectively collecting noble metal includes steps of: adding the noble metal selective collection agent into liquid containing noble metals under acidic conditions; forming an aggregate of the noble metals; and separating and collecting the aggregate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
