摘要：
Processes on the surface of activated carbon interacting with air -saturated cyanid Na[Au(CN)(2)] solution have been reviewed. Formation of anion-radical O-2(-) center dot and radical OH center dot in the cage of the solvent near the surface of the adsorbent has been demonstrated. Impact of those on the sorption activity of the carbon has been discussed.
