The specific surface area of activated carbons has been considered as an important factor when selecting them for gold adsorption applications. It is generally accepted that gold adsorption capacity increases with higher values of specific surface areas; however it has been demonstrated that not all the surface area of an activated carbon is available for gold adsorption. This publication presents the correlations of gold adsorption capacity and gold adsorption density with specific surface area of various activated carbons with different degrees of activation. Results suggest that gold adsorption density on activated carbons is independent of the nature of activated carbons and of degree of activation.
