Abstract

In a process for the oxidation of oxidizable pollutants, contained in aqueous solution, on activated charcoal used as catalyst with feed of oxygen to the aqueous solution, activated charcoal is used which has been heated to red heat at a temperature of above 1000 DEG C in a reducing or inert atmosphere and cooled. For this purpose, activated charcoal can be used which has been heated to red heat at 1100 DEG C in a hydrogen atmosphere for at least 30 minutes. It is also possible to use activated charcoal which has been heated to red heat at 1100 DEG C in vacuo for at least 30 minutes.
