A metal adsorption agent including a chelating agent (A) and a chelating agent (B), wherein the chelating agent (A) is a metal adsorption agent containing a carrier having a glucamine-type functional group, and the chelating agent (B) is a metal adsorption agent containing a carrier having a thiol group, a thiourea group, an amino group, a triazabicyclodecene-inducing group, a thiouronium group, an imidazole group, a sulfonate group, a hydroxy group, an aminoacetate group, an amidoxime group, an aminophosphate group, or any combination of these groups. The carrier of each of the chelating agent (A) and the chelating agent (B) may be silica, a silica component-containing substance, polystyrene, or crosslinked porous polystyrene.
