Summary for Patent: 5,904,832
| Title: | Regeneration of active carbon and polymeric adsorbents |
| Abstract: | Method for the regeneration of active carbon and polymeric adsorbents having oxidizable, organic pollutants adsorbed thereon by electrochemical and chemical means and apparatus therefor. The method involves a desorption step and a decomposition step. Desorption is accomplished in one embodiment by flowing an aqueous stream at a preselected pH through the adsorbent material. Generally, decomposition is accomplished by contacting an aqueous stream containing an organic pollutant with hydroxyl radicals. Sequential or simultaneous desorption and decomposition can also take place during electrolysis in an electrolytic cell. During decomposition the active carbon can be made a carbon bed electrode of the cell. Electrolysis to produce peroxide can take place in the presence of a transition metal or a chelate of a transition metal while feeding an oxygen containing gas to the electrolysis cell. |
