Abstract
The processes occurring on the surface of activated carbons in contact with air-saturated cyanide solution of Na[Au(CN) 2 ] are considered. The formation near the adsorbent surface of anion radical O - 2 · и radical OH · is shown. The influence of these particles on the adsorption activity of coals is discussed.
