Title:
NOBLE METAL ADSORPTION AGENT AND METHOD FOR PRODUCING THE SAME, AND METHOD FOR RECOVERING NOBLE METAL
Document Type and Number:
Japanese Patent JP2014195772
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To produce an adsorption agent capable of separating and recovering noble metals more efficiently as compared with a conventional one and to provide a method for recovering noble metals from a solution containing noble metals such as gold using the adsorption agent.SOLUTION: There is provided a noble metal adsorption agent in which an adsorption agent for recovering noble metals from a solution containing noble metals contains a resin containing an oligomer having an aromatic amino group or a polymer, wherein the aromatic amino group in the resin is an amino group derived from anilines (a), and the adsorption agent contains an aniline-aldehyde resin obtained by reacting anilines (a), aldehyde sources (b) and a reaction catalyst (c).
