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.
