Document Type and Number:
Japanese Patent JP5992796
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for separating and collecting noble metal, capable of efficiently separating and collecting the noble metal from a solution including the noble metal by a simple operation and repeatedly reusing a resin used for separating and collecting the noble metal without remarkable deterioration of adsorption capacity over a long period of time, and suitable for operation on an industrial scale.SOLUTION: The method for separating and collecting noble metal comprises the steps of: (1) contacting a solution including the noble metal with an adsorptive resin impregnated with a liquid organic compound for adsorbing the noble metal to a porous resin to adsorb the noble metal to the adsorptive resin; and (2) contacting the adsorptive resin having the adsorbed noble metal with the liquid organic compound to extract the noble metal in the liquid organic compound.
