<p>1. A process for the production of a highly specific active carbon having a specific BET surface of from 800 to 1800 m**2 /g, as determined by argon adsorption at -196 degrees C, which is covered over its surface with from 0.001 to 0.1 g of a metal, based on 1000 m**2 of carbon surface, characterized in that the active carbon is washed with demineralized water and subsequently left standing in a vacuum of from 10**-4 to 10**-7 bars for 30 minutes to 10 hours at a temperature of from 150 to 300 degrees C in order specifically to modify the surface of the carbon, after which a solution of a suitable metal salt is added to the carbon with stirring in vacuo, optionally followed by cooling, and the carbon now surrounded by vapor is cooled slowly, but at least over a period of 1 hour, to room temperature and subsequently dried.</p> |
