Activated carbon employed for removing weakly held contaminants such as organic chemicals from water, e.g., drinking water, can be recovered or regenerated by back flushing with iodine in water or an organic solvent and then the iodine recovered by reducing it to iodide and the iodide rinsed out of the carbon and reoxidized to iodine. The process can also be used to recover pure organic compounds adsorbed on the carbon.
