Abstract

An activated carbon for adsorbing a noble metal from an aqueous solution containing a noble metal wherein the difference (absolute value) between the zeta potential in a 10 mmol/L aqueous solution of sodium tetraborate and the zeta potential in a 0.01 mmol/L aqueous solution of sodium tetraborate is adjusted to 18 mV or less and the pore volume at a pore radius of 1 nm or less is adjusted to 150 to 500 mm/g. This activated carbon may have a sugar solution decolorization performance of 30% or higher. The aqueous solution containing a noble metal may be a plating waste liquid. The present invention allows noble metal to be adsorbed (or recovered) with good efficiency from a noble metal containing liquid.
