Abstract
Method for the regeneration of active carbon having oxidizable, organic pollutants adsorbed thereon by electrochemical and chemical means and apparatus therefor. The method involves a desorption step prior to a decomposition step. Each step involves conducting electrolysis in a cell using the active carbon as a carbon bed electrode. It is advantageous to conduct the electrolysis in the presence of a transition metal or a chelate of a transition metal while feeding an oxygen containing gas to the electrolysis cell.
